Crowd needs a REST endpoint that client applications can use. Currently client applications can only use the SOAP endpoint to communicate with Crowd.
Here are some examples of using the new REST API.
To search for a particular user, perform a GET request at:
http://YOUR-CROWD-SERVER:8095/rest/usermanagement/1/user?username=<username>
To get all attributes of a particular user, perform a GET request at:
http://YOUR-CROWD-SERVER:8095/rest/usermanagement/1/user/attribute?username=<username>
To add a user, perform a POST request to:
http://YOUR-CROWD-SERVER:8095/rest/usermanagement/1/user
To search for a particular group, perform a GET request at:
http://YOUR-CROWD-SERVER:8095/rest/usermanagement/1/group?groupname=<groupname>
