REST APIs return an empty value[] dataset if user doesn't have permission(no errors)

I use REST APIs pretty frequently so I’m confident we have our server setup for REST APIs(thanks to Jose for the help!).

I’m trying to troubleshoot an issue related to running out of licenses and figured I could poll Ice.BO.AdminSessionSvc/List to start to build up how our license usage is trending. Unfortunately I’m not getting any data back. Do I have to enable this service, or am I doing something dumb? See screenshots below.

I tracked it down to a permissions problem, after changing permissions for the user I connected as to get access to User Tracker the value[] dataset was no longer empty!

So if you are receiving an empty dataset (no errors), it might be a permissions problem…
