I’m attempting to send a PM through the API. (This is intended for a game in which each player is dealt a hand of cards, so it does need to be private.)

I’m sending a request with appropriate values for `raw`, `title` and `target_usernames`, and getting back `{"action":"create_post","errors":["Category can't be blank"]}` with a `422 Unprocessable Entity`.

If I set a category, it ignores `target_usernames` and creates a topic in that category.

If someone is successfully creating and sending PMs using the API, could you post an example with your full request body schema?
