How can I get list of all sId's configured in "Permission groups and access rules" which are configured which can be accessed by our BE service to get details
Hey @pavitra.walia! This currently isn't available for Cloud organizations though there are a few feature requests open for more API endpoints to manage users. If they're picked up I can report back here!
Self-hosted orgs can query this information by joining the user_groups and groups tables of their storage database and then run those queries in a Workflow to be able to access the information externally.
