Forty courier integrations

One API for every courier you ship with.

Ask Royal Mail, DPD, DHL, UPS, FedEx, PostNL and Amazon Shipping what they would charge, all at once in one request, then buy the label and track the parcel without ever learning a carrier's own vocabulary.

Bring your own carrier accounts. Shipstack uses your negotiated rates, not ours.

One request. Every carrier.

Describe the parcel once. Shipstack asks every courier enabled on your account simultaneously and returns their rates sorted cheapest first, with the surcharges itemised, so you can see why a price is what it is.

  • A carrier that times out is reported in failures. It never fails the whole quote.
  • Prices are integer minor units. No floats, no lost pennies.
  • Up to 50 parcels in a single multi-piece consignment.

Five couriers in the time of one.

Rate shopping is only useful if it is fast. Shipstack's quote engine fans out to every enabled carrier concurrently under a fixed latency budget, so the response takes about as long as the slowest single carrier, not the sum of all of them.

Sequentially

~1000ms

Each carrier waits for the one before it.

Shipstack

~200ms

All five asked at once.

Five couriers responding in 200ms each. Measured in the API's own test suite.

Forty integrations, one interface.

Carriers that share a brand rarely share an API. DHL is three separate businesses; DPD and DPD Local are separate contracts. Shipstack treats each as what it is, and hides all of it behind one format.

Integrate once. Never again.

Every carrier's bespoke request and response shape is translated by its adapter into one canonical format. Carrier-specific types are structurally prevented from reaching you. The API's test suite proves it by reflection on every build.

Adding a courier to Shipstack does not change your integration.

How it works
Customs
HS codes, incoterms, IOSS and EORI on international consignments.
Pickup points
Lockers and parcel shops as a destination, validated before booking.
Label formats
PDF, ZPL and PNG, depending on the carrier.
Service options
Signature, age check, insurance, Saturday, cash on delivery, safe place.
Multi-piece
Several parcels in one consignment, with per-parcel references.
Tracking
One normalised status vocabulary across every carrier.

Security

Your carrier credentials are encrypted before they touch the database.

Courier secrets are encrypted at the application layer with AES-256-GCM and stored as binary, never as text. A database backup leak is not a credential leak. The marketing site you are reading holds no shipping data and has no database credentials at all.

Start with a quote request.

Create an account in Shipstack Manager, add the carrier credentials you already hold, and make your first call.
