The Royal Mail Tracking API allows your customers to check on the tracking status of their parcels and mail items. The API provides the latest tracking information, the tracking history, and the proof of delivery information (minus the signature image) for a single mail item.
The API provides the same functionality as the Track & Trace section on the Royal Mail website direct to your customers.
There are no costs to customers for using the Tracking API services, however development costs must be covered by the customer. Royal Mail will not accept any responsibility for these development, implementation and testing costs.
