I've looked everywhere, but I cannot find a way to query Jira for all Service Management users (accountType = "customer").
If I already know the exact accountID /rest/api/3/user?accountId= will return the record of a customer user, but if I try to query for all Jira users in my system, all users of this accountType is filtered out from the resultset.
Also - the Service Management API only provide a POST endpoint for Customers - but no way to query for the list. I know I can get all users for an Organization, but that's not what I'm looking for.
Thanks for any good ideas or pointers
