When I use the following, I am able to get everything except the Details (CustomerPaymentDetail):
entity/Default/22.200.001/CustomerPaymentMethod/?$filter=CustomerID+eq+'C10987654321'+and+PaymentMethod+eq+'CC Visa'+and+ProcCenterID+eq+'procID'+and+CustomerProfileID+eq+'12345678901'
The Details are in the Web service endpoint. Is there a specific URL parameter I need to pass to see it?
