I can use special "system" user fields, such as "Updated Data" and "Created Date", when constructing REST-based searches via the Crowd Query Language (e.g. get a list of users who were updated after July). However, I cannot seem to find a way to simply get these raw values for any specific user via the REST api.
The REST user resoruce offers a way to get most user fields with a request like:
GET /user?username=USERNAME&expand=attributes
But nowhere in the results that come back can I find values for "Updated Data" and "Created Date" or anything like that. I'm know it's possible to get these values via direct SQL-based queires on the Crowd database, but we are specifically looking for a "portable" way to get this info via web services.
