Can you clarify what you mean by this a bit more?
While Simon’s point about these not covering APIs that are implemented by extensions to Discourse (e.g. plugins), these docs are official in the sense that we do maintain them.
That’s not to say we don’t have a fair bit of room to improve when it comes the server side API documentation, and the API itself, but I did want to understand your feedback about the documentation that does exist there a bit better.
