Hi @sec_tech ! I have this problem a couple of months ago, I could not get the Get Access/Manage Access work to achieve your objective, even putting the Manage Access inside a Loop.
I could do it with 2 HTTP Request actions, first one calls the IDN API to retrieve user’s entitlements, then put response in a Loop, and inside a the loop another HTTP Request which it calls IDN API to revoke entitlement.
