Getting a list of all users through REST API

I want to create a new Project through the REST API and assign the Project Lead.  This means I need to use the /user/picker or /user/search endpoints so the user can select any active user in JIRA.

Both endpoints have a mandatory username/query parameter with an implicit leading wildcard.  This means I can't construct a list of users programatically by sending off a query for each letter in the alphabet as /user/search?username=a returns Adam and Edward.

This is a pretty basic thing to do so I'm sure others have come across the same problem.

Hi Karen,

This issue has been reported in the following case:

Please note, from the request, it does mention the following:

In various environments, it has been observed that setting username to one of the following characters will do the trick:

  • /rest/api/latest/user/search?username="" (double quotes)
  • /rest/api/latest/user/search?username='' (single quotes)
  • /rest/api/latest/user/search?username=. (dot)
  • /rest/api/latest/user/search?username=% (percent)
  • /rest/api/latest/user/search?username=_ (underscore)

Also, maxResults and startAt seem to be functioning.

You can give this a try in your environment and see if you're able to get any further, but do note that it doesn't seem to work for all Jira setups.

Kind Regards,

Hi Karen,

I am now sure whether you are using Cloud or not, however you should be able to get the list of all the assignable users for a project by using:

I hope this helps.

Actually the same endpoint exists for JIRA Server too:

...It's true that there are projects in Jira; but they are merely a way to cut off issues, to tell them apart from other sections of work and to apply rules that are specific to that team (the schemes)....
