Hi Duong, Thank you for posting your concern.
I can see that you encountered the USER_PERMISSION_DENIED error and it occurs when authenticating as a user with access to a manager account but not specifying login-customer-id in the request. With this, could you confirm if you already tried the suggestion in the error message? If you haven't tried yet, then please follow the instruction below: 1. First determine the manager account that you want to link with the client account 2. Generate Oauth2 credential using email address that have access to the manager account and configure it to your client library 2. Set the customer ID of the manager account to the login_customer_id field. Ensure to remove the hyphen ('-') of the customer ID before setting it up 3. Set the customer ID of client account to the customer_id field and without hyphen ('-') as well 4. Try the API request again If the error persists, please provide the complete request and response logs with request ID and request header generated on your end. You can provide it via Reply privately to author option. If this option is not available, then send it instead on this email address googleadsapi-supp...@google.com.
