Hi Travis, The error that you received 'Client is unauthorized to retrieve access tokens using this method' implies that the service account needs to be authorized properly. This <https://developers.google.com/identity/protocols/OAuth2ServiceAccount#delegatingauthority> guide will help you setup GSuite authorization for service accounts. However, do you actually need service account functionality, or could you simply use offline access as described in the alternative to service accounts <https://developers.google.com/adwords/api/docs/guides/service-accounts#alt>section of the guide. Either way, please let me know if you have further questions.
