I’m using Discourse through the API as a community backend. There are certain categories that should be restricted for regular users so that they can’t create topics or edit topic titles. However, they should be able to see the threads and reply to them. All this should be done via the API (using an admin token) on behalf of those users. Is there a way I can implement that through proper security and API calls? E.g. it’s enough if I can force-create a post in a restricted category on behalf of a regular user (using an admin key/user), but I can’t find that case in API documentation.
