createShipment

Creates a shipment with the data specified in the shipment request.
An error will be returned when the shipment exists already.
Optionally various operations like label preparation and label output can be applied on the shipment. A complete processing including the pickup assignment is also possible.
The operations are handled asynchronously, so operation processing errors and label documents are not part of the response. They can be retrieved with a syncShipments or getShipments call.
