Crowd REST resources

Available:	Crowd 2.1 and later.
API version:	1

Note that these might be out of date. For the current versions of Crowd see https://developer.atlassian.com/server/crowd/rest/latest

The Crowd REST APIs allow you to address the Crowd data entities as 'resources'. This means that the data entities are identified by URIs and operated on by HTTP requests (GET, POST, PUT and DELETE). Whenever you GET one of these resources, you receive a representation encoded in XML or JSON. Below are details of the resources made available by the APIs.

Overview

Crowd offers a set of REST APIs for use by applications connecting to Crowd.

Please note the main difference between Crowd APIs and the APIs of other applications like JIRA and Confluence: In Crowd, an application is the client of Crowd, whereas in JIRA/Confluence a user is the client. For example, when authenticating a request to a Crowd REST resource via basic authentication, the application name and password is used (and not a username and password). Keep this in mind when using the REST APIs.

URIs for a Crowd REST API resource have the following structure: With context:

1
2
http://host:port/context/rest/api-name/api-version/resource-name

Or without context:

1
2
http://host:port/rest/api-name/api-version/resource-name

API Name - `usermanagement`

In Crowd 2.1, the only api-name available is usermanagement. This is the API that allows an application to interact with the Crowd server.

Examples

With context:

1
2
http://myhost.com:8095/crowd/rest/usermanagement/1/user?username=USERNAME
http://localhost:8095/crowd/rest/usermanagement/latest/user?username=USERNAME

Or without context:

1
2
http://crowd.myhost.com:8095/rest/usermanagement/1/user?username=USERNAME
http://crowd.myhost.com:8095/rest/usermanagement/latest/user?username=USERNAME

Please refer to the Crowd REST API usage guide for a description of the common factors in the APIs, including a full explanation of the URI format, authentication, API versions, HTTP response codes, and so on.

User Authentication Resource

No session is created in user authentication. An application can simply ask Crowd "is this username/password valid?" This is the primary purpose of the Authentication resource.

Successful Authentication Response

Description:

POST /authentication?username=USERNAME

Authenticates a user

Status Code:

200 (OK) if successful 400 (Bad Request) if unsuccessful

Response Body (XML):

As below

Search Resource

All Search resource methods have optional start-index and max-results query params.

Request Body (XML)	Description
1 2 `<?xml version="1.0" encoding="UTF-8"?> <property-search-restriction> <property> <name>email</name> <type>STRING</type> </property> <match-mode>EXACTLY_MATCHES</match-mode> <value>bob@example.net</value> </property-search-restriction>`	POST `/search?entity-type=user` Searches for users (returning the usernames) with the specified search restriction
As above	POST `/search?entity-type=user&expand=user` Searches for users with the specified search restriction
As above	POST `/search?entity-type=group` Searches for groups (returning the group names) with the specified search restriction
As above	POST `/search?entity-type=group&expand=group` Searches for groups with the specified search restriction

From Crowd 2.2 onwards, you can perform searches using the Crowd Query Language. Use a GET, rather than a POST, and provide the restriction parameter with CQL:

Request Body (XML):

As above

Descrition:

GET /search?entity-type=ENTITY_TYPE&restriction=CQL_QUERY

Searches for entities of ENTITY_TYPE (either 'user' or 'group') with the specified search restriction (as Crowd Query Language).

Crowd SSO Token Resource

The Crowd SSO token resource allows an application to authenticate a user and receive an SSO token from the Crowd server. The application decides what to do with the SSO token, though normally this SSO token is set as a cookie in the user's browser.

Crowd SSO Session

<?xml version="1.0" encoding="UTF-8"?>

Unsuccessful Crowd SSO Session Creation Response

<?xml version="1.0" encoding="UTF-8"?>
<error>
  <reason>...</reason>
  <message>Error message</message>
</response>

Request Body (XML)	Description
1 2 `<?xml version="1.0" encoding="UTF-8"?> <authentication-context> <username>my_username</username> <password>my_password</password> <validation-factors> <validation-factor> <name>remote_address</name> <value>127.0.0.1</value> </validation-factor> </validation-factors> </authentication-context>`	POST `/session` Optional `validate-password` and `duration` query params Create new session token valid for `duration` seconds, or for the server default session timeout if no `duration` is specified or if `duration` is longer than the server default session timeout Either user password needs to be valid or `validate-password` query param must be set to `false` If an ongoing session already exists for the same authentication credentials and validation factors, then that session token is returned. Status: 201 (Created) with successful response as above if the session creation was successful or an ongoing session already existed 400 (Bad Request) with unsuccessful response as above if the user authentication details are incorrect (e.g., bad password, inactive user, user does not have permission to authenticate with the application). Response Body (XML): See Crowd SSO Session entity above
None.	DELETE `/session?username=USERNAME` Optional `exclude` query param Invalidate all tokens for a given user name. Optionally, a token key can be saved from invalidation if specified in the `exclude` param Status: 204 (No Content) if successful 404 (Not Found) if the user is not found 400 (Bad request) if the application is not found
None.	GET `/session/{token`} Retrieves the token with the authenticated user expanded Status: 200 (OK) if successfully retrieved 404 (Not Found) if the token is not found Response Body (XML): See Crowd SSO Session entity above

Validating the token keeps the SSO session alive. Status: 200 (OK) if successful 400 (Bad request) if the validation factors are incorrect 404 (Not Found) if the token cannot be found Response Body (XML): See Crowd SSO Session entity above
	DELETE `/session/{token`} Invalidates the token Status: 204 (No Content)
