Everything, behind one REST API

Quote rates, create shipments, fetch labels and read tracking from the same versioned API. Predictable JSON in and out, with clear errors and idempotency on writes.

Secure by default, simple to call

Create scoped API tokens for each system and send them as a Bearer header. Limit what each token can do, rotate them anytime, and keep production and test keys apart — no OAuth dance to set up.

Shipment events, pushed to you

Subscribe once and Smart Send posts an event to your endpoint as parcels move — booked, label ready, in transit, delivered. No polling, and delivery is retried until your endpoint confirms.
