Hello Sundaram, Thank you for reaching out to us.
Since you're using service accounts when accessing the API, have you tried the steps mentioned on this guide? Please 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. If the issue still persists even after following the provided guide, kindly share to us the complete logs (request and response with request-id). You can send the requested details via the Reply privately to author option. If this option is not available, you may send the details directly to our googleadsapi-supp...@google.com alias instead.
