Between 10:34am to 10:52 am PT today, users of our API were receiving invalid_auth errors when making a request to a range of API methods. We noticed that both bot and user tokens were being used to call various methods of our API. These requests were being erroneously rejected with the invalid_token error due to a database issue.
We have since fixed the issue. Thank you for hanging in there, and our apologies for any inconvenience.
