Hi Team,
we are using rest api to get all user_group
rest api = <sp_site>/_api/web/sitegroups
Using this API, we are getting few user_group only,
but when we are trying to assign asl for any document or directory through SP site, that time we are getting all available user_group.
Regards,
Pankaj Kumar

When are calling rest API = _api/web/sitegroups
