Hello Steve, The USER_PERMISSION_DENIED <https://developers.google.com/adwords/api/docs/common-errors#AuthorizationError.USER_PERMISSION_DENIED> error is experienced when there is no link between the manager account authenticated in the request and the client account specified or when the OAuth credentials used are for a user who do not have access to the client customer ID specified or any of its manager accounts. You could use CustomerService.getCustomers() <https://developers.google.com/adwords/api/docs/reference/v201710/CustomerService#getcustomers> which returns details of all the customers directly accessible by the user authenticating the call and then use the ManagedCustomerService <https://developers.google.com/adwords/api/docs/reference/v201710/ManagedCustomerService> to determine the client accounts linked to a manager account.
If you continue to have an issue with this, could you provide us the SOAP request and response logs for the API call along with the email address used for authentication, so we can take a look and assist further. You can respond via *Reply privately to author *option while replying.
