How to know when a user is assigned to a group?

Hi, I’m trying to get a time-stamp property/ any information regarding when a particular user( based on userId) is added to a particular group( based on group Id).

Is there a way to achieve this?/ How can I get that?

That info isn’t saved on the user or group object, but it’s available in the system log.

You could poll/watch the system log for the group.user_membership.add event, and look for events where the targets are the userId and groupId you are interested in:

Joël’s blog post and loghook tool may be useful:



Thanks for the answer, That should suffice.
