What happens when a carrier fails upstream from the API?
If a carrier isn't responding upstream from us, the API will return 400 and 500 errors.
Also, if a carrier isn't responding from a multi-carrier rating call, we will still display all available rates from all available carriers. The unresponsive carrier will return a rate error message that can be found in the Shipment Object's
