What you can track​

Ocean shipments​

Track ocean freight using:

  • Container numbers
  • Bill of lading numbers
  • Booking numbers

Get available shipment milestones, vessel information, ports, estimated arrival, and current status.

Air shipments​

Track air cargo using an air waybill (AWB) number.

Get available shipment milestones, flight information, airports, estimated arrival, and current status.

Check carrier coverage​

Before sending a tracking request, check whether a carrier or airline is supported by Tracking One.

Use the API to discover:

Build your integration once and let Tracking One handle carrier-specific tracking data.

One API. Multiple carriers.​

Instead of integrating with individual carriers and airlines, connect to Tracking One and access tracking data through a consistent REST API.

  • Ocean + Air — Track freight across multiple modes.
  • Unified API — Use one integration instead of multiple carrier APIs.
  • Structured data — Receive tracking information in a consistent format.
  • Carrier coverage — Check support before you track.

Start here​

Every integration is the same short path: check that the carrier is covered, create an API key, send a number, read the JSON back.

  • Getting started — the base URL, your first request, what the response and error codes mean, rate limits and what a lookup costs.
  • Authentication — creating an API key, sending it as a bearer token, and keeping it off the browser.

API reference​

Explore the available endpoints and request parameters.

The OpenAPI documents behind these pages are published as they are, if you would rather import them into Postman or generate a client — download them here.

Tracking on your own site​

If you would rather not build the front end, two drop-in trackers — a container widget and an air waybill widget — render the whole result card from a <div> and a <script> tag, against an endpoint of yours that holds the API key.
