Hi Jakub, My apologies for the delayed response. Allow me to provide support to your concern.
The USER_PERMISSION_DENIED error occurs when authenticating as a user with access to a manager account but not specifying login-customer-id in the request. With this, you need to specify the login-customer-id as the manager account ID without hyphens (-). If the issue persists after trying the provided suggestion, then please provide the following details below via Reply privately to author option to further investigate: Customer ID email address / user account that has access to the MCC account and used to generate Oauth2 credential complete request and response logs with request ID generated on your end where we can see this error Regards, Ernie John Blanca Tacata Google Ads API Team ref:_00D1U1174p._5004Q2Dxld3:ref -- -- =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ Also find us on our blog: https://googleadsdeveloper.blogspot.com/ =~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~=~ You received this message because you are subscribed to the Google Groups "AdWords API and Google Ads API Forum" group.
