Hi,
You have now reached the Google Ads API support team. We hope that today is going well for you.
Please note that our support channel can provide assistance related to
Google Ads API technical issues only. Could you please confirm, if you are creating a new campaign in the Google Ads UI then you encountered the said error
"Operation not permitted for current customer"? If so, the appropriate support team to reach regarding Google Ads UI is the
Google Ads Product support team as they are more knowledgeable when it comes to Google Ads account and Google Ads user interface.
If you are using the Google Ads API to create a new campaign, then you may share to us the complete
request and
response logs and
request-id, that generated on your end where we can see the error occurred. If you haven't yet, logging can be enabled by referring to this
guide and by using the DEBUG log setting.
For security purposes, you can provide it via the Reply privately to author option. If this option is not available, then send it instead on this email address
googleadsapi-support@google.com.
Best regards,
