Granular API key restriction missing a lot of endpoints


I am looking for a way to enable access to our Forum’s API but limit this access to the /groups endpoint or even better to the AddGroupMember Method. The granular settings in the admin panel only seem to allow to limit the access of a newly generated API key to a smaller selection of endpoints. Is there any other way to get this done?

Thank you in advance!

If you’re trying to limit who can add to the group can’t you just make a user that has access only to that group? Say configure the group so that group owners can manage members? You don’t even need api key restrictions as you have user restrictions, right?
