Currently, the GoToWebinar access token expires after 365 days. However, it does not give you any warning that the token has expired. This happened in the middle of a customer webinar series so customers were not able to register.
It would be great if you could either 1) make it so the token doesn't expire, or 2) provide a warning to users that the token will/has expired. Even some wording in the tokens area that indicates it has experied would be helpful. Currently it just says API 403 error.
