System for Cross-Domain Identity Management: Protocol
draft-ietf-scim-api-12
The System for Cross-Domain Identity Management (SCIM) specification is an HTTP based protocol that makes managing identities in multi-domain scenarios easier to support through a standardized services. Examples include but are not limited to enterprise to cloud service providers, and inter-cloud based scenarios. The specification suite seeks to build upon experience with existing schemas and deployments, placing specific emphasis on simplicity of development and integration, while applying existing authentication, authorization, and privacy models. SCIM's intent is to reduce the cost and complexity of user management operations by providing a common user schema and extension model and a service protocol defined by this document.

This document is subject to BCP 78 and the IETF Trust's Legal Provisions Relating to IETF Documents (http://trustee.ietf.org/license-info) in effect on the date of publication of this document. Please review these documents carefully, as they describe your rights and restrictions with respect to this document.

The SCIM Protocol is an application-level, HTTP protocol for provisioning and managing identity data on the web and in cross-domain environments such as enterprise to cloud, or inter-cloud scenarios. The protocol supports creation, modification, retrieval, and discovery of core identity resources such as Users and Groups, as well as custom resources and resource extensions.
This document is intended as a guide to SCIM protocol usage for both SCIM HTTP service providers and HTTP clients who may provision information to service providers or retrieve information from them.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in [RFC2119]. These keywords are capitalized when used to unambiguously specify requirements of the protocol or application features and behavior that affect the interoperability and security of implementations. When these words are not capitalized, they are meant in their natural-language sense.
For purposes of readability examples are not URL encoded. Implementers MUST percent encode URLs as described in Section 2.1 of [RFC3986].
Throughout this documents all figures MAY contain spaces and extra line-wrapping for readability and space limitations. Similarly, some URI's contained within examples, have been shortened for space and readability reasons.
Because SCIM builds on the HTTP protocol, it does not itself define a scheme for authentication and authorization. SCIM depends on standard HTTP authentication schemes. Implementers SHOULD support existing authentication/authorization schemes. In particular, OAuth2 (see [RFC6749], [RFC6750]) is RECOMMENDED. Appropriate security considerations of the selected authentication and authorization schemes SHOULD be taken. Because this protocol uses HTTP response status codes as the primary means of reporting the result of a request, servers are advised to respond to unauthorized or unauthenticated requests using the 401 response code in accordance with Section 3.1 of [RFC7235].
All examples show an OAuth2 bearer token [RFC6750] (though it is not required); e.g.,
GET /Users/2819c223-7f76-453a-919d-413861904646 HTTP/1.1
Host: example.com
Authorization: Bearer h480djs93hd8
When processing requests, the service provider SHOULD consider the subject performing the request and whether the action is appropriate given the subject and the resource affected by the request. The subject performing the request is usually determined from the Authorization header present in the request.
The SCIM protocol specifies well-known endpoints and HTTP methods for managing resources defined in the core schema; i.e., User and Group resources correspond to /Users and /Groups respectively. Service providers that support extended resources SHOULD define resource endpoints using the convention of pluralizing the resource name defined in the extended schema by appending an 's'. Given there are cases where resource pluralization is ambiguous; e.g., a resource named Person is legitimately Persons and People. Clients SHOULD discover resource endpoints via the /ResourceTypes endpoint.
| Resource | Endpoint | Operations | Description |
|---|---|---|---|
| User | /Users | GET [get-resource], POST [create-resource], PUT [edit-resource-with-put], PATCH [edit-resource-with-patch], DELETE [delete-resource] | Retrieve, Add, Modify Users |
| Group | /Groups | GET [get-resource], POST [create-resource], PUT [edit-resource-with-put], PATCH [edit-resource-with-patch], DELETE [delete-resource] | Retrieve, Add, Modify Groups |
| Service Provider Config | /ServiceProvider Configs | GET [get-resource] | Retrieve service provider's configuration |
| Resource Type | /ResourceTypes | GET [get-resource] | Retrieve supported resource types |
| Schema | /Schemas | GET [get-resource] | Retrieve one or more supported schemas. |
| Bulk | /Bulk | POST [bulk-resources] | Bulk updates to one or more resources |
| Search | [prefix]/.search | POST [query-post] | Search from system root or within a resource endpoint for one or more resource types using POST. |
All requests to the service provider are made via HTTP Methods as per Section 4.3 [RFC7231] on a URL derived from the Base URL. Responses are returned in the body of the HTTP response, formatted as JSON. Error status codes SHOULD be transmitted via the HTTP status code of the response (if possible), and SHOULD also be specified in the body of the response (see Section 3.10).
To create new resources, clients send HTTP POST requests to the resource endpoint such as: /Users or /Groups.
The server SHALL process attributes according to the following mutability rules:
When the service provider successfully creates the new resource, an HTTP response SHALL be returned with HTTP status 201 ("Created"). The response body SHOULD contain the service provider's representation of the newly created resource. The URI of the created resource SHALL included in the HTTP Location header and in JSON resource representation under the attribute meta.location. Since the server is free to alter and/or ignore POSTed content, returning the full representation can be useful to the client, enabling it to correlate the client and server views of the new resource.
If the service provider determines creation of the requested resource conflicts with existing resources; e.g., a User resource with a duplicate userName, the service provider MUST return an HTTP Status 409, with scimType error code of uniqueness as per Section 3.10.
Below, in the following example, a client sends a POST request containing a User to the /Users endpoint.
POST /Users HTTP/1.1
Host: example.com
Accept: application/scim+json
Content-Type: application/scim+json
Authorization: Bearer h480djs93hd8
Content-Length: ...
{
"schemas":["urn:ietf:params:scim:schemas:core:2.0:User"],
"userName":"bjensen",
"externalId":"bjensen",
"name":{
"formatted":"Ms. Barbara J Jensen III",
"familyName":"Jensen",
"givenName":"Barbara"
}
}
In response to the example request above, the server signals a successful creation with an HTTP status code 201 (Created) and returns a representation of the resource created.
HTTP/1.1 201 Created
Content-Type: application/scim+json
Location:
https://example.com/v2/Users/2819c223-7f76-453a-919d-413861904646

},
"name":{
"formatted":"Ms. Barbara J Jensen III",
"familyName":"Jensen",
"givenName":"Barbara"
},
"userName":"bjensen"
}
When adding a resource to a specific endpoint, the meta attribute resourceType SHALL be set by the HTTP service provider to the corresponding resource type for the endpoint. For example, /Users will set resourceType to User, and /Groups will set resourceType to Group.
Resources are retrieved via opaque, unique URLs or via Query. The attributes returned are defined in the server's attribute schema (see Section 10 [I-D.ietf-scim-core-schema]) and request parameters (see Section 3.7). By default, resource attributes returned in a response are those whose schema returned setting is always or default.
To retrieve a known resource, clients send GET requests to the resource endpoint; e.g., /Users/{id} or /Groups/{id}, or /Schemas/{id}.
If the resource exists the server responds with HTTP Status code 200 (OK) and includes the result in the body of the response.
The below example retrieves a single User via the /Users endpoint.
GET /Users/2819c223-7f76-453a-919d-413861904646
Host: example.com
Accept: application/scim+json
Authorization: Bearer h480djs93hd8
The server responds with:
HTTP/1.1 200 OK

The SCIM protocol defines a standard set of query parameters that can be used to filter, sort, and paginate to return zero or more resources in a query response. Queries MAY be made against a single resource or a resource type endpoint (e.g. /Users). SCIM service providers MAY support additional query parameters not specified here and SHOULD ignore any query parameters they do not recognize.
Responses MUST be identified using the following URI: urn:ietf:params:scim:api:messages:2.0:ListResponse. The following attributes are defined for responses:
A query that does not return any matches SHALL return success (HTTP Status 200) with totalResults set to a value of 0.
The query example below requests the userName for all Users:
GET /Users?attributes=userName
Host: example.com
Accept: application/scim+json
Authorization: Bearer h480djs93hd8
The following is an example response to the query above:
HTTP/1.1 200 OK
Content-Type: application/scim+json
{
"schemas":["urn:ietf:params:scim:api:messages:2.0:ListResponse"],
"totalResults":2,
"Resources":[
{
"userName":"bjensen"
},
{
"userName":"jsmith"
}
]
}
Queries MAY be performed against a SCIM resource object, a resource type endpoint, or a SCIM server root. For example:
filter=(meta.resourceType eq User) or (meta.resourceType eq Group)
A query against a server root indicates that ALL resources within the server SHALL be included subject to filtering. A filter expression using meta.resourceType MAY be used to restrict results to one or more specific resource types (to exclude others). For example:
If a SCIM service provider determines that too many results would be returned (e.g. because a client queried a resource type endpoint or the server base URI), the server SHALL reject the request by returning an HTTP response with status 400 and json attribute scimType set to tooMany (see Table 8).
When processing query operations across endpoints that include more than one SCIM resource type (e.g. a query from the server root endpoint), filters MUST be processed as outlined in Section 3.2.2.2. For filtered attributes that are not part of a particular resource type, the service provider SHALL treat the attribute as if there is no attribute value. For example, a presence or equality filter for an undefined attribute evaluates as FALSE.
Filtering is an OPTIONAL parameter for SCIM service providers. Clients MAY discover service provider filter capabilities by looking at the filter attribute of the ServiceProviderConfig (see Section 8 [I-D.ietf-scim-core-schema]). Clients MAY request a subset of resources by specifying the filter query parameter containing a filter expression. When specified only those resources matching the filter expression SHALL be returned. The expression language that is used in the filter parameter supports references to attributes and literals.
Attribute names and attribute operators used in filters are case insensitive. For example, the following two expressions will evaluate to the same logical value:
filter=userName Eq "john"
filter=Username eq "john"
The filter parameter MUST contain at least one valid Boolean expression. Each expression MUST contain an attribute name followed by an attribute operator and optional value. Multiple expressions MAY be combined using the two logical operators. Furthermore expressions can be grouped together using "()".
The operators supported in the expression are listed in the following table.
| Operator | Description | Behavior |
|---|---|---|
| eq | equal | The attribute and operator values must be identical for a match. |
| ne | not equal | The attribute and operator values are not identical. |
| co | contains | The entire operator value must be a substring of the attribute value for a match. |
| sw | starts with | The entire operator value must be a substring of the attribute value, starting at the beginning of the attribute value. This criterion is satisfied if the two strings are identical. |
| ew | ends with | The entire operator value must be a substring of the attribute value, matching at the end of the attribute value. This criterion is satisfied if the two strings are identical. |
| pr | present (has value) | If the attribute has a non-empty or non-null value, or if it contains a non-empty node for complex attributes there is a match. |
| gt | greater than | If the attribute value is greater than operator value, there is a match. The actual comparison is dependent on the attribute type. For string attribute types, this is a lexicographical comparison and for DateTime types, it is a chronological comparison. For Integer attributes it is a comparison by numeric value. Boolean and Binary attributes SHALL cause a failed response (HTTP Status 400) with scimType of invlaidFiler. |
| ge | greater than or equal | If the attribute value is greater than or equal to the operator value, there is a match. The actual comparison is dependent on the attribute type. For string attribute types, this is a lexicographical comparison and for DateTime types, it is a chronological comparison. For Integer attributes it is a comparison by numeric value. Boolean and Binary attributes SHALL cause a failed response (HTTP Status 400) with scimType of invlaidFiler. |
| lt | less than | If the attribute value is less than operator value, there is a match. The actual comparison is dependent on the attribute type. For string attribute types, this is a lexicographical comparison and for DateTime types, it is a chronological comparison. For Integer attributes it is a comparison by numeric value. Boolean and Binary attributes SHALL cause a failed response (HTTP Status 400) with scimType of invlaidFiler. |
| le | less than or equal | If the attribute value is less than or equal to the operator value, there is a match. The actual comparison is dependent on the attribute type. For string attribute types, this is a lexicographical comparison and for DateTime types, it is a chronological comparison. For Integer attributes it is a comparison by numeric value. Boolean and Binary attributes SHALL cause a failed response (HTTP Status 400) with scimType of invlaidFiler. |
| Operator | Description | Behavior |
|---|---|---|
| and | Logical And | The filter is only a match if both expressions evaluate to true. |
| or | Logical or | The filter is a match if either expression evaluates to true. |
| not | Not function | The filter is a match if the expression evaluates to false. |
| Operator | Description | Behavior |
|---|---|---|
| ( ) | Precedence grouping | Boolean expressions may be grouped using parentheses to change the standard order of operations; i.e., evaluate OR logical operators before logical AND operators. |
| [ ] | Complex attribute filter grouping | Service providers MAY support complex filters where expressions MUST be applied to the same value of a parent attribute specified immediately before the left square bracket ("["). The expression within square brackets ("[" and "]") MUST be a valid filter expression based upon sub-attributes of the parent attribute. Nested expressions MAY be used. See examples below. |
SCIM filters MUST conform to the following ABNF rules as per [RFC5234] below:
FILTER = attrExp / logExp / valuePath / *1"not" "(" FILTER ")"
valuePath = attrPath "[" FILTER "]"
; FILTER uses sub-attribs of a parent attrPath
ATTRNAME = ALPHA *(nameChar)
nameChar = "-" / "_" / DIGIT / ALPHA
attrPath = [URI ":"] ATTRNAME *1subAttr
; SCIM attribute name
; URI is SCIM "schema" URI
subAttr = "." ATTRNAME
; a sub-attribute of a complex attribute
attrExp = (attrPath SP "pr") /
(attrPath SP compareOp SP compValue)
compValue = false / null / true / number / string
; rules from JSON (RFC7159)
compareOp = "eq" / "ne" / "co" /
"sw" / "ew" /
"gt" / "lt" /
"ge" / "le"
logExp = FILTER ("and" / "or") FILTER
Figure 1: ABNF Specification of SCIM Filters
In the above ABNF, the compValue (comparison value) rule is built on JSON Data Interchange format ABNF rules as specified in [RFC7159], DIGIT and ALPHA are defined per Appendix B.1 of [RFC5234] and, URI is defined per Appendix A of [RFC3986].
Filters MUST be evaluated using standard order of operations [Order-Operations]. Attribute operators have the highest precedence, followed by the grouping operator (i.e, parentheses), followed by the logical AND operator, followed by the logical OR operator.
If the specified attribute in a filter expression is a multi-valued attribute, the resource MUST match if any of the instances of the given attribute match the specified criterion; e.g. if a User has multiple emails values, only one has to match for the entire User to match. For complex attributes, a fully qualified Sub-Attribute MUST be specified using standard attribute notation [attribute-notation]. For example, to filter by userName the parameter value is userName and to filter by first name, the parameter value is name.givenName.
Providers MAY support additional filter operations if they choose. Providers MUST decline to filter results if the specified filter operation is not recognized and return a HTTP 400 error with an appropriate human readable response. For example, if a client specified an unsupported operator named 'regex' the service provider should specify an error response description identifying the client error; e.g., 'The operator 'regex' is not supported.'
String type attributes are case insensitive by default unless the attribute type is defined as case exact. Attribute comparison operators 'eq', 'co', and 'sw' MUST perform caseIgnore matching for all string attributes unless the attribute is defined as case exact. By default all string attributes are case insensitive.
Clients MAY query by schema or schema extensions by using a filter expression including the "schemas" attribute.
The following are examples of valid filters. Some attributes (e.g. rooms and rooms.number) are hypothetical extensions and are not part of SCIM core schema:
filter=userName eq "bjensen" filter=name.familyName co "O'Malley" filter=userName sw "J" filter=title pr filter=meta.lastModified gt "2011-05-13T04:42:34Z" filter=meta.lastModified ge "2011-05-13T04:42:34Z" filter=meta.lastModified lt "2011-05-13T04:42:34Z" filter=meta.lastModified le "2011-05-13T04:42:34Z" filter=title pr and userType eq "Employee" filter=title pr or userType eq "Intern" filter= schemas eq "urn:ietf:params:scim:schemas:extension:enterprise:2.0:User" filter=userType eq "Employee" and (emails co "example.com" or emails co "example.org") filter=userType ne "Employee" and not (emails co "example.com" or emails co "example.org") filter=userType eq "Employee" and (emails.type eq "work") filter=userType eq "Employee" and emails[type eq "work" and value co “@example.com"] filter=emails[type eq "work" and value co “@example.com"] or ims[type eq "xmpp" and value co "@foo.com"] filter=addresses[state eq "CA" and rooms[type eq "bedroom" and number gt 2]]
Figure 2: Example Filters
Sort is OPTIONAL. Sorting allows clients to specify the order in which resources are returned by specifying a combination of sortBy and sortOrder URL parameters.
Pagination parameters can be used together to "page through" large numbers of resources so as not to overwhelm the client or service provider. Pagination is not session based hence clients SHOULD never assume repeatable results. For example, a request for a list of 10 resources beginning with a startIndex of 1 may return different results when repeated as a resource in the original result could be deleted or new ones could be added in-between requests. Pagination parameters and general behavior are derived from the OpenSearch Protocol [OpenSearch].
The following table describes the URL pagination parameters.
| Parameter | Description | Default |
|---|---|---|
| startIndex | The 1-based index of the first query result. A value less than 1 SHALL be interpreted as 1. | 1 |
| count | Non-negative Integer. Specifies the desired maximum number of query results per page; e.g., 10. A negative value SHALL be interpreted as 0. A value of 0 indicates no resource results are to be returned except for totalResults. | None. When specified the service provider MUST NOT return more results than specified though MAY return fewer results. If unspecified, the maximum number of results is set by the service provider. |
The following table describes the query response pagination attributes specified by the service provider.
| Element | Description |
|---|---|
| itemsPerPage | Non-negative Integer. Specifies the number of query results returned in a query response page; e.g., 10. |
| totalResults | Non-negative Integer. Specifies the total number of results matching the client query; e.g., 1000. |
| startIndex | The 1-based index of the first result in the current set of query results; e.g., 1. |
For example, to retrieve the first 10 Users set the startIndex to 1 and the count to 10:
GET /Users?startIndex=1&count=10
Host: example.com
Accept: application/scim+json
Authorization: Bearer h480djs93hd8
The response to the query above returns metadata regarding paging similar to the following example (actual resources removed for brevity):
{
"totalResults":100,
"itemsPerPage":10,
"startIndex":1,
"schemas":["urn:ietf:params:scim:api:messages:2.0:ListResponse"],
"Resources":[{
...
}]
}
The following attributes control which attributes SHALL be returned with a returned resource. SCIM clients MAY use up to one of these two OPTIONAL parameters which MUST be supported by SCIM service providers:
Clients MAY execute queries without passing parameters on the URL by using the HTTP POST verb combined with the '/.search' path extension. The inclusion of '/.search' on the end of a valid SCIM endpoint SHALL be used to indicate the HTTP POST verb is intended to be a query operation.
To create a new query result set, a SCIM client sends an HTTP POST request to the desired SCIM resource endpoint (ending in '/.search'). The body of the POST request MAY include any of the parameters as defined in Section 3.2.2.
Query requests MUST be identified using the following URI: 'urn:ietf:params:scim:api:messages:2.0:SearchRequest'. The following attributes are defined for query requests:
After receiving a HTTP POST request, a response is returned as specified in Section 3.2.2.
The following example shows an HTTP POST Query request with search parameters attributes, filter, and count included:
POST /.search
Host: example.com
Accept: application/scim+json
Content-Type: application/scim+json
Authorization: Bearer h480djs93hd8
Content-Length: ...
{
"schemas": ["urn:ietf:params:scim:api:messages:2.0:SearchRequest"],
"attributes": ["displayName", "userName"],
"filter":
"(displayName sw \"smith\") and (meta.resourceType eq \"User\")",
"startIndex": 1,
"count": 10
}

...
]
}

Resources can be modified in whole or in part via PUT or PATCH, respectively. Implementers MUST support PUT as specified in Section 4.3 [RFC7231]. Resources such as Groups may be very large hence implementers SHOULD support HTTP PATCH [RFC5789] to enable partial resource modifications.
HTTP PUT is used to perform a full update of a resource's attributes. Clients that MAY have previously retrieved the entire resource in advance and revised it, MAY replace the resource using an HTTP PUT. Because SCIM resource identifiers are typically assigned by the service provider, HTTP PUT MUST NOT be used to create new resources.
As the operation intent is to replace all attributes, SCIM clients MAY send all attributes regardless of each attribute's mutability. The server will apply attribute by attribute replace according to the following attribute mutability rules:
If an attribute is required, clients MUST specify the attribute in the PUT request.
Unless otherwise specified a successful PUT operation returns a 200 OK response code and the entire resource within the response body, enabling the client to correlate the client's and the service provider's views of the updated resource. Example:
PUT /Users/2819c223-7f76-453a-919d-413861904646
Host: example.com
Accept: application/scim+json
Content-Type: application/scim+json

HTTP PATCH is an OPTIONAL server function that enables clients to update one or more attributes of a SCIM resource using a sequence of operations to add, remove, or replace values. The general form of the SCIM patch request is based on JavaScript Object Notation (JSON) Patch [RFC6902]. One difference between SCIM patch and JSON patch is that SCIM servers do not support array indexing and may not support all [RFC6902] operation types.
The body of each request MUST contain the following schemas attribute with the URI value of: urn:ietf:params:scim:api:messages:2.0:PatchOp.
The body of an HTTP PATCH request MUST contain the attribute Operations, whose value is an array of one or more patch operations. Each patch operation object MUST have exactly one "op" member, whose value indicates the operation to perform and MAY be one of add, remove, or replace. The semantics of each operation are defined in the following sub-sections.
The following is an example representation of a PATCH request showing the basic JSON structure (non-normative):
{ "schemas": ["urn:ietf:params:scim:api:messages:2.0:PatchOp"],
"Operations":[
{
"op":"add",
"path":"members",
"value":[
{
"display": "Babs Jensen",
"$ref": "https://example.com/v2/Users/2819c223...413861904646",
"value": "2819c223-7f76-453a-919d-413861904646"
}
]
},
... + additional operations if needed ...
]
}
Figure 5: Example JSON body for SCIM PATCH Request
A path attribute value is a String containing an attribute path describing the target of the operation. The path attribute is OPTIONAL for add and replace and is REQUIRED for remove operations. See relevant operation sections below for details.
The path attribute is described by the following ABNF syntax rule:
PATH = attrPath / valuePath [subAttr]
Figure 6: SCIM Patch PATH Rule
The ABNF rules, attrPath, valuePath, and subAttr are defined in Section 3.2.2.2. The valuePath rule allows specific values of a complex, multi-valued attribute to be selected.
Valid examples of path values are as follows:
"path":"members"
"path":"name.familyName"
"path":"addresses[type eq \"work\"]"
"path":"members[value eq
\"2819c223-7f76-453a-919d-413861904646\"]"
"path":"members[value eq
\"2819c223-7f76-453a-919d-413861904646\"].displayName"
Figure 7: Example Path Values
Each operation against an attribute MUST be compatible with the attribute's mutability and schema as defined in the Attribute Types Section of [I-D.ietf-scim-core-schema]. For example, a client MUST NOT modify an attribute that has mutability readOnly or immutable. However, a client MAY add a value to an immutable attribute if the attribute had no previous value. An operation that is not compatibile with an attribute's mutability or schema SHALL return the appropriate HTTP response status code and a JSON detail error response as defined in Section 3.10.
The attribute notation rules described in Section 3.8 apply for describing attribute paths. For all operations, the value of the schemas attribute on the SCIM service provider's representation of the resource SHALL be assumed by default. If one of the PATCH operations modifies the schemas attribute, subsequent operations SHALL assume the modified state of the schemas attribute. Clients MAY implicitly modify the schemas attribute by adding (or replacing) an attribute with its fully qualified name including schema URN. For example, adding the attribute urn:ietf:params:scim:schemas:extension:enterprise:2.0:User:employeeNumber, automatically adds the value urn:ietf:params:scim:schemas:extension:enterprise:2.0:User to the resource's schemas attribute.
Each patch operation represents a single action to be applied to the same SCIM resource specified by the request URI. Operations are applied sequentially in the order they appear in the array. Each operation in the sequence is applied to the target resource; the resulting resource becomes the target of the next operation. Evaluation continues until all operations are successfully applied or until an error condition is encountered.
For a multi-valued attributes, a patch operation that sets a value's primary attribute to true, SHALL cause the server to automatically set primary to false for any other values in the array as only one value MAY be primary.
A patch request, regardless of the number of operations, SHALL be treated as atomic. If a single operation encounters an error condition, the original SCIM resource MUST be restored, and a failure status SHALL be returned.
If a request fails, the server SHALL return an HTTP response status code and a JSON detail error response as defined in Section 3.10.
On successful completion, the server MUST return either a 200 OK response code and the entire resource (subject to the "attributes" query parameter - see Additional Retrieval Query Parameters [addtl-retrieval-query-params] ) within the response body, or a 204 No Content response code and the appropriate response headers for a successful patch request. The server MUST return a 200 OK if the "attributes" parameter is specified on the request.
The add operation is used to add a new attribute value to an existing resource.
The operation MUST contain a value member whose content specifies the value to be added. The value MAY be a quoted value OR it may be a JSON object containing the sub-attributes of the complex attribute specified in the operation's path.
The result of the add operation depends upon what the target location indicated by path references:
The following example shows how to add a member to a group. Some text removed for readability ("..."):
PATCH /Groups/acbf3ae7-8463-4692-b4fd-9b4da3f908ce

"value": "2819c223-7f76-453a-919d-413861904646"
}
]
}
]
}
If the user was already a member of this group, no changes should be made to the resource and a success response should be returned. The server responds with either the entire updated Group or no response body:
HTTP/1.1 204 No Content Authorization: Bearer h480djs93hd8 ETag: W/"b431af54f0671a2" Location: "https://example.com/Groups/acbf3ae7-8463-4692-b4fd-9b4da3f908ce"
The following example shows how to add one or more attributes to a User resource without using a path attribute.
PATCH /Users/2819c223-7f76-453a-919d-413861904646
Host: example.com
Accept: application/scim+json
Content-Type: application/scim+json

"op":"add",
"value":"{
"emails":[
{
"value":"babs@jensen.org",
"type":"home"
}
],
"nickname":"Babs"
}]
}
In the above example, an additional value is added to the multi-valued attribute emails. The second attribute, nickname is added to the User resource. If the resource already had an existing nickname, the value is replaced per the processing rules above for single-valued attributes.
The remove operation removes the value at the target location specified by the required attribute path. The operation performs the following functions depending on the target location specified by path :
If an attribute is removed or becomes unassigned and is defined as a required attribute or a read-only attribute, the server SHALL return an HTTP response status code and a JSON detail error response as defined in Section 3.10 with a scimType error of mutability.
The following example shows how to remove a member from a group. As with the previous example, the "display" sub-attribute is optional. If the user was not a member of this group, no changes should be made to the resource and a success response should be returned.
Note that server responses have been omitted for the rest of the PATCH examples.

Clients request resource removal via DELETE. Service providers MAY choose not to permanently delete the resource, but MUST return a 404 error code for all operations associated with the previously deleted Id. Service providers MUST also omit the resource from future query results. In addition the service provider SHOULD NOT consider the deleted resource in conflict calculation. For example if a User resource is deleted, a CREATE request for a User resource with the same userName as the previously deleted resource should not fail with a 409 error due to userName conflict.

The SCIM bulk operation is an optional server feature that enables clients to send a potentially large collection of resource operations in a single request. The body of a a bulk operation contains a set of HTTP resource operations using one of the API supported HTTP methods; i.e., POST, PUT, PATCH or DELETE.
Bulk requests are identified using the following URI: urn:ietf:params:scim:api:messages:2.0:BulkRequest. Bulk responses are identified using the following URI: urn:ietf:params:scim:api:messages:2.0:BulkResponse. Bulk requests and bulk responses share many attributes. Unless otherwise specified, each attribute below is present in both bulk requests and bulk responses.
The following Singular Attribute is defined in addition to the common attributes defined in SCIM core schema.
The following Complex Multi-valued Attribute is defined in addition to the common attributes defined in core schema.
If a bulk job is processed successfully the HTTP response code 200 OK MUST be returned, otherwise an appropriate HTTP error code MUST be returned.
The service provider MUST continue performing as many changes as possible and disregard partial failures. The client MAY override this behavior by specifying a value for the failOnErrors attribute. The failOnErrors attribute defines the number of errors that the service provider should accept before failing the remaining operations returning the response.
To be able to reference a newly created resource the attribute bulkId MUST be specified when creating new resources. The bulkId is defined by the client as a surrogate identifier in a POST operation (see Section 3.5.2). The service provider MUST return the same bulkId together with the newly created resource. The bulkId can then be used by the client to map the service provider id with the bulkId of the created resource.
A SCIM service provider MAY elect to optimize a sequence operations received (e.g. to improve processing performance). When doing so, the service provider MUST ensure the clients intent is preserved and the same stateful result is achieved as for non-optimized processing. For example, before a User can be added to a Group, they must first be created. Processing these requests out of order, might result in a failure to add the new User to the Group.
The service provider MUST try to resolve circular cross references between resources in a single bulk job but MAY stop after a failed attempt and instead return the status code 409 Conflict. The following example exhibits the potential conflict.

A SCIM client can, within one bulk operation, create a new User, a new Group and add the newly created User to the newly created Group. In order to add the new User to the Group the client must use the surrogate id attribute, bulkId, to reference the User. The bulkId attribute value must be pre-pended with the literal bulkId:; e.g., if the bulkId is 'qwerty', the value is bulkId:qwerty. The service provider MUST replace the string bulkId:qwerty with the permanent resource id once created.
To create multiple distinct requests, each with their own bulkId, the SCIM client specifies different bulkId values for each separate request.
The following example creates a User with the userName 'Alice' and a Group with the displayName 'Tour Guides' with Alice as a member. Notice that each operation has its own bulkId value. However, the second operation (whose bulkId is ytrewq) refers to the bulkId of qwerty in order to add Alice to new 'Tour Guides' group.

}
The service provider response MUST include the result of all processed operations. A location attribute that includes the resource's endpoint MUST be returned for all operations excluding failed POSTs. The status attribute includes information about the success or failure of one operation within the bulk job. The attribute status MUST include the code attribute that holds the HTTP response code that would have been returned if a single HTTP request would have been used. If an error occurred the status MUST also include the description attribute containing a human readable explanation of the error.
"status": "201"
The following is an example of a status in a failed operation.
"status": "400",
"response":{
"schemas": ["urn:ietf:params:scim:api:messages:2.0:Error"],
"scimType":"invalidSyntax"
"detail":

"status":"400"
}
The following example shows how to add, update, and remove a user. The failOnErrors attribute is set to '1' indicating the service provider should return on the first error. The POST operation's bulkId value is set to 'qwerty' enabling the client to match the new User with the returned resource id '92b725cd-9465-4e7d-8c16-01f8e146b87a'.

The service provider MUST define the maximum number of operations and maximum payload size a client may send in a single request. These limits MAY be retrieved from the Service Provider Configuration (see 'bulk' in Section 8 of [I-D.ietf-scim-core-schema]). If either limits are exceeded the service provider MUST return the HTTP response code 413 Request Entity Too Large. The returned response MUST specify the limit exceeded in the body of the error response.
The following example the client sent a request exceeding the service provider's max payload size of 1 megabyte:
POST /v2/Bulk Host: example.com Accept: application/scim+json Content-Type: application/scim+json Authorization: Bearer h480djs93hd8 Content-Length: 4294967296 …
In response to the over-sized request, the server responds with the following error:
HTTP/1.1 413 Request Entity Too Large
Content-Type: application/scim+json
{
"schemas":["urn:ietf:params:scim:api:messages:2.0:Error"],
"status": "413",
"detail":
"The size of the bulk operation exceeds the maxPayloadSize (1048576)."
}
Servers MUST accept requests and respond with JSON structured responses using UTF-8 encoding [RFC3629], UTF-8 SHALL be the default encoding format.
GET /Users/2819c223-7f76-453a-919d-413861904646.scim
Host: example.com
Clients using other encodings MUST specify the format in which the data is submitted via HTTP header Content-Type as specified in Section 3.1.1.5 [RFC7231] and MAY specify the desired response data format via an HTTP Accept header ( Section 5.3.2 [RFC7231] ); e.g., Accept: application/scim+json or via URI suffix; e.g.,
Service providers MUST support the accept header Accept: application/scim+json and SHOULD support header Accept: application/json both of which specify JSON documents conforming to [RFC7159]. The format defaults to application/scim+json if no format is specified.
Singular attributes are encoded as string name-value-pairs in JSON; e.g.,
"attribute": "value"
Multi-valued attributes in JSON are encoded as arrays; e.g.,
"attributes": [ "value1", "value2" ]
Elements with nested elements are represented as objects in JSON; e.g,
"attribute": { "subattribute1": "value1", "subattribute2": "value2" }
For any SCIM operation where a resource representation is returned (e.g. HTTP GET), the attributes returned are defined as the minimum attribute set plus default attributes set. The minimum set are those attributes whose schema have returned set to always. The default attribute set are those attributes whose schema have returned set to default.
Clients MAY request a partial resource representation on any operation that returns a resource within the response by specifying either of the mutually exclusive URL query parameters attributes OR excludedAtributes as follows:
.
GET /Users/2819c223-7f76-453a-919d-413861904646?attributes=userName

}
}
All operations share a common scheme for referencing simple and complex attributes. In general, attributes are identified by prefixing the attribute name with its schema URN separated by a ':' character; e.g., the core User resource attribute 'userName' is identified as urn:ietf:params:scim:schemas:core:2.0:User:userName. Clients MAY omit core schema attribute URN prefixes though MUST fully qualify extended attributes with the associated resource URN; e.g., the attribute 'age' defined in urn:ietf:params:scim:schemas:exampleCo:2.0:hr is fully encoded as urn:ietf:params:scim:schemas:exampleCo:2.0:hr:age. A Complex attributes' Sub-Attributes are referenced via nested, dot ('.') notation; i.e., {urn}:{Attribute name}.{Sub-Attribute name}. For example, the fully qualified path for a User's givenName is urn:ietf:params:scim:schemas:core:2.0:User:name.givenName All facets (URN, attribute and Sub-Attribute name) of the fully encoded Attribute name are case insensitive.
A client MAY use a URL of the form <base-URI>/Me as a URI alias for the User or other resource associated with the currently authenticated subject for any SCIM operation. A service provider MAY respond in ONE of 3 ways:
When using the SCIM Create Resource command (HTTP POST) with the /Me alias, the desired resourceType being created is at the discretion of the service provider based on the authenticated subject (if not anonymous) making the request and any request body attributes (e.g. schemas). See Section 6.3 for information on security considerations related to this operation.
The SCIM Protocol uses the HTTP status response status codes defined in Section 6 [RFC7231] to indicate operation success or failure. In addition to returning a HTTP response code implementers MUST return the errors in the body of the response in the client requested format containing the error response and, per the HTTP specification, human-readable explanations. Error responses are identified using the following schema URI: urn:ietf:params:scim:api:messages:2.0:Error. The following attributes are defined for a SCIM error response using a JSON body:
Implementers SHOULD handle the identified HTTP status codes as described below.
| Status | Applicability | Suggested Explanation |
|---|---|---|
| 307 TEMPORARY REDIRECT | GET, POST, PUT, PATCH, DELETE | The client is directed to repeat the same HTTP request at the location identified. The client SHOULD NOT use the location provided in the response as a permanent reference to the resource and SHOULD continue to use the original request URI [RFC7231]. |
| 308 PERMANENT REDIRECT | GET, POST, PUT, PATCH, DELETE | The client is directed to repeat the same HTTP request at the location identified. The client SHOULD use the location provided in the response as the permanent reference to the resource [RFC7238]. |
| 400 BAD REQUEST | GET, POST, PUT, PATCH, DELETE | Request is unparseable, syntactically incorrect, or violates schema |
| 401 UNAUTHORIZED | GET, POST, PUT, PATCH, DELETE | Authorization failure |
| 403 FORBIDDEN | GET, POST, PUT, PATCH, DELETE | Server does not support requested operation |
| 404 NOT FOUND | GET, PUT, PATCH, DELETE | Specified resource (e.g., User) or end-point, does not exist |
| 409 CONFLICT | POST, PUT, PATCH, DELETE | The specified version number does not match the resource's latest version number or a service provider refused to create a new, duplicate resource |
| 412 PRECONDITION FAILED | PUT, PATCH,D ELETE | Failed to update as resource {id} changed on the server last retrieved |
| 413 REQUEST ENTITY TOO LARGE | POST | {"maxOperations": 1000,"maxPayload": 1048576} |
| 500 INTERNAL SERVER ERROR | GET, POST, PUT, PATCH, DELETE | An internal error. Implementers SHOULD provide descriptive debugging advice |
| 501 NOT IMPLEMENTED | GET, POST, PUT, PATCH, DELETE | Service Provider does not support the request operation; e.g., PATCH |
For HTTP Status 400 (Bad Request) responses, the following detail error types are defined:
| scimType | Description | Applicability |
|---|---|---|
| invalidFilter | The specified filter syntax was invalid (does not comply with Figure 1) or the specified attribute and filter comparison combination is not supported. | GET(Section 3.2.2), POST (Search - Section 3.2.3), PATCH (Path Filter - Section 3.3.2) |
| tooMany | The specified filter yields many more results than the server is willing calculate or process. For example, a filter such as (userName pr) by itself would return all entries with a userName and MAY not be acceptable to the service provider. | GET(Section 3.2.2), POST (Search - Section 3.2.3) |
| uniqueness | One or more of attribute values is already in use or is reserved. | POST (Create - Section 3.1), PUT (Section 3.3.1), PATCH (Section 3.3.2) |
| mutability | The attempted modification is not compatible with the target attributes mutability or current state (e.g. modification of an immutable attribute with an existing value). | PUT (Section 3.3.1), PATCH (Section 3.3.2) |
| invalidSyntax | The request body message structure was invalid or did not conform to the request schema. | POST (Search - Section 3.2.2, Create - Section 3.1, Bulk - Section 3.5), PUT (Section 3.3.1) |
| invalidPath | The path attribute was invalid or malformed (see Figure 6). | PATCH (Section 3.3.2) |
| noTarget | The specified path did not yield an attribute or attribute value that could be operated on. This occurs when the specified path value contains a filter that yields no match. | PATCH (Section 3.3.2) |
| invalidValue | A required value was missing, or the value specified was not compatible with the operation or attribute type (see Section 2.1 [I-D.ietf-scim-core-schema]). | GET (Section 3.2.2), POST (Create - Section 3.1, Query - Section 3.2.2), PUT (Section 3.3.1), PATCH (Section 3.3.2) |
| invalidVers | The specified SCIM protocol version is not supported (see Section 3.11). | GET (Section 3.2.2), POST (ALL), PUT (Section 3.3.1), PATCH (Section 3.3.2), DELETE (Section 3.4) |
Note that in the table above (Table 8), the applicability table applies to the normal HTTP method but MAY apply within a SCIM Bulk operation (via HTTP POST).

Error example in response to a PUT request.
[[Editor's note: while the detail error codes seem to have consensus, there is a question about whether the error codes should be extensible so that individual service providers may define site specific codes. Should all scimTypes be URIs, so that scimTypes can be registered via IANA? Should there be a separate field defined for this purpose? Or, should custom signalling (for non-protocol/schema errors, be out of scope?]]
The Base URL MAY be appended with a version identifier as a separate segment in the URL path. At this time of this specification, the identifier is 'v2'. If specified, the version identifier MUST appear in the URL path immediately preceding the resource endpoint and conform to the following scheme: the character 'v' followed by the desired SCIM version number; e.g., a version 'v2' User request is specified as /v2/Users. When specified service providers MUST perform the operation using the desired version or reject the request. When omitted service providers SHOULD perform the operation using the most recent SCIM protocol version supported by the service provider.
The SCIM protocol supports resource versioning via standard HTTP ETags Section 2.3 [RFC7233]. Service providers MAY support weak ETags as the preferred mechanism for performing conditional retrievals and ensuring clients do not inadvertently overwrite each others changes, respectively. When supported SCIM ETags MUST be specified as an HTTP header and SHOULD be specified within the 'version' attribute contained in the resource's 'meta' attribute.
Example:
POST /Users HTTP/1.1
Host: example.com
Content-Type: application/scim+json
Authorization: Bearer h480djs93hd8
Content-Length: ...
{
"schemas":["urn:ietf:params:scim:schemas:core:2.0:User"],
"userName":"bjensen",
"externalId":"bjensen",
"name":{
"formatted":"Ms. Barbara J Jensen III",
"familyName":"Jensen",
"givenName":"Barbara"
}
}
The server responds with an ETag in the response header and meta structure.

},
"name":{
"formatted":"Ms. Barbara J Jensen III",
"familyName":"Jensen",
"givenName":"Barbara"
},
"userName":"bjensen"
}
With the returned ETag, clients MAY choose to retrieve the resource only if the resource has been modified.
Conditional retrieval example using If-None-Match Section 3.2 [RFC7233] header:
GET /Users/2819c223-7f76-453a-919d-413861904646?attributes=displayName
Host: example.com
Accept: application/scim+json
Authorization: Bearer h480djs93hd8
If-None-Match: W/"e180ee84f0671b1"
If the resource has not changed the service provider simply returns an empty body with a 304 "Not Modified" response code.
If the service providers supports versioning of resources the client MAY supply an If-Match Section 3.1 [RFC7233] header for PUT and PATCH operations to ensure that the requested operation succeeds only if the supplied ETag matches the latest service provider resource; e.g., If-Match: W/"e180ee84f0671b1"
To increase the likelihood that the input and comparison of unicode usernames and passwords will work in ways that make sense for typical users throughout the world there are special string preparation and comparison methods (PRECIS) that MUST be followed for usernames and passwords. Before comparing or evaluating uniqueness of a userName or password attribute, service providers MUST use the "PRECIS" profile described in Sections 4 and 5 respectively of [I-D.ietf-precis-saslprepbis] and is based on the "PRECIS" framework specification [I-D.ietf-precis-framework].
A single service provider may expose the SCIM protocol to multiple clients. Depending on the nature of the service, the clients may have authority to access and alter resources initially created by other clients. Alternatively, clients may expect to access disjoint sets of resources, and may expect that their resources are inaccessible by other clients. These scenarios are called "multi-tenancy", where each client is understood to be or represent a "tenant" of the service provider. Clients may also be multi-tenanted.
The following common cases may occur:
Service providers may implement any subset of the above cases.
Multi-Tenancy is OPTIONAL. The SCIM protocol does not define a scheme for multi-tenancy.
The SCIM protocol does not prescribe the mechanisms whereby clients and service providers interact for:
The service provider MAY use the authentication mechanism (Section 2) to determine the identity of the client, and thus infer the associated Tenant.
For implementations where a client is associated with more than one Tenant, the service provider MAY use one of the following methods for explicit specification of the Tenant.
If any of these methods of allowing the client to explicitly specify the Tenant are employed, the service provider should ensure that access controls are in place to prevent or allow cross-tenant use cases.
The service provider should consider precedence in cases where a client may explicitly specify a Tenant while being implicitly associated with a different Tenant.
In all of these methods, the {tenant_id} is a unique identifier for the Tenant as defined by the service provider.
Considerations for a Multi-Tenant Implementation:
The service provider may choose to implement SCIM ids which are unique across all resources for all Tenants, but this is not required.
The externalId, defined by the client, is required to be unique ONLY within the resources associated with the associated Tenant.
The SCIM Protocol layers on top of Hypertext Transfer Protocol and thus subject to the security considerations of HTTP Section 9 [RFC7230] and its related specifications.
SCIM resources (e.g., Users and Groups) can contain sensitive information. Therefore, SCIM clients and service providers MUST implement TLS. Which version(s) ought to be implemented will vary over time, and depend on the widespread deployment and known security vulnerabilities at the time of implementation. At the time of this writing, TLS version 1.2 [RFC5246] is the most recent version, but has very limited actual deployment, and might not be readily available in implementation toolkits. TLS version 1.0 [RFC5246] is the most widely deployed version, and will give the broadest interoperability.
As mentioned in ,Section 9.4 [RFC7231], SCIM clients requesting information using query filters using HTTP GET SHOULD give consideration to the information content of the filters and whether their exposure in a URI would represent a breach of security or confidentiality through leakage in a web browsers or server logs. This is particularly true for information that is legally considered "personally identifiable information" or is otherwise restricted by privacy laws. In these situations to ensure maximum security and confidentiality, clients SHOULD query using HTTP POST (see Section 3.2.3 ).
HTTP/1.1 403 FORBIDDEN
{
"schemas": ["urn:ietf:params:scim:api:messages:2.0:Error"],
"Errors":[
{
"description":
"Query filter involving 'name' is restricted or confidential",
"error":"confidential_restricted"
}
]
}
Servers that receive HTTP GET requests using filters that contain restricted or confidential information SHOULD respond with HTTP status 403 indicating the operation is FORBIDDEN. A detailed error, confidential_restricted may be returned indicating the request must be submitted using POST. A non-normative example:
If a SCIM service provider accepts anonymous requests such as SCIM resource creation requests (via HTTP POST), appropriate security measures should be put in place to prevent or limit exposure to attacks. The following counter-measures MAY be used:
As an HTTP based protocol, implementers of SCIM SHOULD consider all security considerations of the HTTP/1.1 as enumerated in Section 1 [RFC7230]
As stated in Section 2.7.1 [RFC7230], a SCIM client MUST NOT generate the userinfo (i.e. username and password) component (and its "@" delimiter) when an "http" URI reference is generated with a message as they are now disallowed in HTTP.
An attacker may obtain valid username/password combinations from the SCIM service provider's underlying database by gaining access to the database and/or launching injection attacks. This could lead to unintended disclosure of username/password combinations. The impact may extend beyond the domain of the SCIM service provider if the data was provisioned from other domains.
Administrators should undertake industry best practices to protect the storage of credentials and in particular SHOULD follow recommendations outlines in Section 5.1.4.1 [RFC6819]. These recommendations include but are not limited to:
