Hi Gary,
TrackingUrlTemplate at the account level needs to be set using
CustomerService. Once you create a client account using
ManagedCustomerService, you need to set the
clientCustomerId header to the ID of the newly created account and then perform a
CustomerService.mutate() operation to update the tracking URL template of this customer account. If this value is not being set correctly, could you send over your SOAP request and response logs so I can take a look? Please use
