New API - Offline Barcoding Number Range for Royal Mail Shipments

A new API has been added to allow customers who are using barcoding (generating labels outside of Pro Shipping) to request a barcode number range. This API will obtain a barcode range for the requested service, and return this range in the API response for the customer to store in their labelling system. For more information, see the API Reference page and the Royal Mail API section.
