Hi,

Thank you for reaching out to the Google Ads API support team.

Based on the information provided, I understand that you are getting CUSTOMER_NOT_ALLOWLISTED_FOR_THIS_FEATURE error while creating the client account using the Google Ads API. In order to further investigate, kindly provide us with the complete API logs (request and response logs with request-id and request header) generated at your end to better assist you further. 

If you are using a client library and haven't enabled the logging yet, I would request you to enable logging for the specific client library that you are using. You can refer to the guides Java, .Net, PHP, Python, Ruby or Perl to enable logging at your end. For REST interface requests, you can enable logging via the curl command by using the -i flag.

You can send the details via Reply privately to the author option, or direct private reply to this email.
 

This message is in relation to case "ref:!00D1U01174p.!5004Q02vGbIY:ref" (ADR-00270057)

Thanks,
