The Royal Mail Shipping REST API provides the functionality for customers to take a shipping transaction from creation to collection. It is a service offered via Royal Mail to request for the creation, update, cancellation of a shipment, printing of a label, printing of international Customs documents, requesting 2D bar code ranges, requesting 1D Item ID ranges, creation and printing of a manifest.
Built on industry standards, the API provides a simple and low cost method for customers to integrate with Royal Mail, and allows them to get shipping quickly.
There are no costs to customers for using the Shipping API's services, however customers’ own development costs must be covered by the customer developing the solution. Royal Mail will not accept any responsibility for these development, implementation and testing costs.
Customers should address initial inquiries regarding development of systems for these purposes to their account handler.
