invalid_session

Session expired or invalid · HTTP 401

What causes this

The session token is malformed or no longer valid. Sessions are also invalidated deliberately by a password reset, which signs out every existing session.

How to fix it

Log in again. If you are calling the API from a server, use an API key rather than a session — sessions are for the console.
