title: JIRA REST API -Get project roles/groups of a user
body: <p>What is the REST call to list all the project roles of a user.</p>
  
  <p>I could get the groups by using:
  <a href="http://XXX/rest/api/2/user?username=XXX&amp;expand=groups" rel="nofollow">http://XXX/rest/api/2/user?username=XXX&amp;expand=groups</a>.</p>
  
  <p>I want the project role results by sending username but not project name.</p>
