Hello,
Looks like the attachment is missing. If you are using our new
Google Ads API and facing the user_permission_denied error. Mostly it could be the reason that not setting the
login-customer-id in the headers while making the API call. You could refer this
blog post for more information. If you are facing the error even after setting
login-customer-id as your manager account authenticating the call, please share the Client Customer Id,
login-customer-id and email address of the user authenticating the API call along with the complete error logs to investigate further. Please use reply privately to the user option while sharing the information requested.
Regards,
Sai Teja, Google Ads API Team
