New API – Pre-Allocate Royal Mail Tracking Number

A new API has been added to allow a Royal Mail tracking number to be requested before creating a shipment.

This API will pre-allocate a tracking number without generating a shipment or label. The tracking number can then be used in the Create Shipment request to create a shipment using the same service and destination associated with the pre-allocated tracking number.

For more information, see the API Reference page and the Royal Mail API section.
