Hello,
I have tried to access the AdWords API from a test account after creating a production account to get the developer token. However, running the get_campaigns,py throws the following error:
google.auth.exceptions.RefreshError: ('unauthorized_client: Unauthorized', '{\n "error" : "unauthorized_client",\n "error_description" : "Unauthorized"\n}')
The client_id, client_secret, and the refresh_token are created for the test account and I am sure that they are populated in the googleads.yaml correctly.
Thank you,
