API usage (danbooruup)

With some images I've been trying to upload I get an "access denied" message when I hit a tab where danbooru is.

Tried looking the help files but I didn't find anywhere if the api/add_post is being restricted to some group of users (maybe it is because doing so through the API it bypasses the moderation queue?)

Just curiosity though.

You should update your extension. Then have it point to http://miezaru.donmai.us/post/create.xml for uploads, and http://miezaru.donmai.us/tag/index.xml for getting the tags.

Ah ok so now that's how it works.
I have the latest version but on the Preferences of the add-on it's still saying "URL of the api/add_post" which confused me
