The PrimeFreight Tracking API gives you programmatic access to your shipments across both ocean and air freight. It exposes three resources: shipments, containers, and container events. All responses are JSON. To begin, authenticate with a POST to obtain a token, then create a tracking request with a container number or bill of lading. Once tracking resolves, the shipment, container, and event data are available through read-only (GET) endpoints. Base URL
All timestamps are ISO 8601 with a timezone offset.
The API returns the latest recorded state of each shipment and container. Fields that haven’t been set yet come back as null rather than an error, so handle nulls on your side.
