400 - Virtual Service Not Found
Tip
The virtual_service_not_found error code will be returned if an attempt is made to allocate a shipment with a "virtual service", but the reference provided does not identify a valid service.
A "virtual service reference" is a pointer to one of either a carrier service or a carrier service group.
If you attempt to allocate with a "virtual service", you can provide either a valid carrier service reference or a valid service group reference. If the reference you provide does not match either a valid carrier service or a valid service group then a virtual_service_not_found error will be returned.
