Hi Martin, Thanks for reaching out to us.
Could you confirm if you already followed the instructions discussed in this document, especially the prerequisite? If yes and the issue still persists, then could you provide the following details via Reply privately to author option to further investigate? User account / email address that you've used in setting up service account through API Customer ID Complete request and response logs with request ID generated on your end where we can see the issue However, kindly note that we strongly recommend using OAuth2 desktop app or web app flow instead of service accounts unless you need a domain-specific feature (for example, impersonation). OAuth2 desktop app and web app flows do require an initial user interaction for granting access to the account, but are much simpler to set up.
