Version 2 of the Shipment API is live. It is fully backwards compatible: existing integrations keep working, and you can adopt the new features one at a time.

Webhooks for every status change

Subscribe once and receive a signed event whenever a shipment changes state, from booked to delivered. No more polling the events endpoint.

Idempotent bookings

Send an Idempotency-Key header with POST /shipments and retries after a dropped subspace link will never book the same cargo twice.

Migrating

Read the Shipment API reference for the full list of changes.
