Getting an API key and making your first call

API keys are created in Developer in the dashboard. A key is shown once, when it is created — store it somewhere safe, because we keep only a hash of it.

Your first call

Every endpoint takes the key as a bearer token. Look up a container by number, or a shipment by bill of lading; both return the same tracking document.

Limits

Requests are rate-limited per key, per minute, and the ceiling depends on your plan. A call that is refused returns a clear status rather than failing silently, so a client can back off and retry.

Webhooks

Rather than polling, you can register a webhook and be told when a shipment moves. Deliveries retry on failure and a persistently failing endpoint is disabled automatically, with an email first.
