I had created a access token prior before from google api to connect to Alteryx. However, just couple of months ago, it began to respond in error. Is there something i need to do extra that can help connect alteryx training to the API?
The access tokens will have a limited lifetime, you should be using the refresh token to generate the new access token, refer to the following URL for more details - https://developers.google.com/identity/protocols/oauth2
The refresh token also expires after a specific lifetime, in that case, a new refresh token should be retrieved.
