This page is part of the MediaWiki Action API documentation.

To make sure your bot doesn't edit while logged out, the action API provides an assert parameter which you can add to any request.

• assert=user: Checks that your account is logged in
• assert=bot: Checks that your account has the "bot" user right

If the assertion fails, error codes of assertuserfailed or assertbotfailed will be returned.

Checking if you are logged in

If you simply want to check whether you are logged into the action API, you can issue a request with parameters action=query&assert=user. This will return a simple blank response ({} in the JSON format) if you are indeed logged in, or the assertuserfailed error if not.

Normally, you will not need to do this. Instead, add the assert=user parameter to all requests that should be made by a logged-in user.
