Parcel Perform Shipments API
Create, retrieve, list, and update shipments in a Parcel Perform account. A shipment carries the carrier/courier code, tracking number, sender and recipient details, and (in the v5.2.0 response) related returns, rating, line item, and collection point objects. This is the system of record that ties a merchant order to a trackable parcel across Parcel Perform's carrier network.
