The Parcelforce Tracking API exposes a web service that allows customers enquire on the tracking status of mail items which are being handled through the Parcelforce network. There are two API operations available which provide both single and multi-item tracking services. The first API operation provides single item parcel tracking functionality based on Parcelforce consignment number, parcel label, foreign parcel label or senders reference for one account. The second API operation provides registration, parcel searching and multiple parcel searching functionality based on customer number (or sender reference) and account information. There are no costs to customers for using the PFW Tracking API, however customers own development costs must be covered by the customer developing the solution. Royal Mail Group will not accept any responsibility for these development, implementation and testing costs.
