Hi Kevin, The SERVICE_ACCESS_DENIED <https://developers.google.com/adwords/api/docs/reference/v201802/CampaignService.AuthorizationError.Reason#SERVICE_ACCESS_DENIED> error means that the user authorizing the API call doesn't have access to the specific service, or in your scenario, is not allowed to use the CampaignService. If indeed that the user (email address you used to generate the OAuth2 credentials) does not have access, then you could request an Admin user on the account to grant that user the necessary access level. You may refer to this guide <https://support.google.com/adwords/answer/1704346?hl=en> to know more about the access levels in AdWords.
However, since you confirmed that you are already an administrator of your AdWords account and this error still persists, then can you provide to me the specific email address you used in your authentication so I can further investigate?
