Revokes user multi site licenses by their IDs. Important note: Before revoking a multi site license, the system identifies the user associated with the license and checks the available user seats across all sites (belonging to your third party) where the user is invited. If there are not enough available site user seats, the license will not be revoked. The response data will indicate which licenses were successfully revoked, which were not with the site(s) data that is preventing the revocation.
