API integration · Live
A REST API between your system and four carriers.
Running a bespoke OMS, an ERP, or something nobody else has heard of? The parcel2ship REST API takes an order as JSON and gives you back the whole dispatch pipeline: validation, cheapest-carrier routing, labels, manifests, and webhook events carrying status and tracking back to your system.
How it connects
POST an order, get a shipping pipeline
One integration surface: send orders over authenticated REST and they enter the same routing, labelling and manifesting flow as every native channel.
Webhooks back to you
Order status and tracking events are pushed to your endpoint as they happen, so your system stays the source of truth for your customers.
Carrier complexity abstracted
Royal Mail, Evri, DPD and DX behind one schema — including customs paperwork for international and Northern Ireland — without integrating four carrier APIs yourself.
Out the other side
Every Custom REST API parcel auto-routed to the cheapest eligible service

Where is the API documentation?

How does my system learn about tracking numbers?
Via webhooks: parcel2ship pushes status and tracking events to an endpoint you nominate, as each shipment progresses.
