Hi Michael, Thank you for reaching out. For CustomerService, the resulting list of customers is based on the OAuth credentials used in the request. The request returns a list of all accounts that the credentials are able to act upon directly. If your customer's account is returning a blank response, it is possible that the credentials used in the request are not an admin for any of the accounts in your customer's account or it does not manage any accounts.
Can you clarify what data you expect to retrieve from GoogleAdsService? Additionally, can you please provide the complete detailed logs of the request and response in which you are experiencing the issue so that I can take a closer look? Please provide these details via the "Reply privately to author" option to ensure your sensitive data is protected.
