Hello,
The ID provided in the logs is a MCC ID, you will have to specify the
clientCustomerId of the target AdWords client account. It is required for all the API calls except CustomerService and ReportDefinitionService. Once you provide the clientCustomerId and make an API call, this will return results for the Expanded Text ads in your account.
If you continue to have an issue with this, could you enable logging and provide us the complete SOAP request and response logs along with the clientCustomerId, so I can take a look? Please use Reply privately to author option to provide the details.
Regards,
Bharani, AdWords API Team
