ShipEngine

ShipEngine Is an API. Somebody Still Has to Wire It to Everything Else.

ShipEngine is a shipping API: multi-carrier rate comparison, label generation, address validation, and tracking, meant to be called from your own code rather than clicked through in a dashboard. We don't set up your ShipEngine account or write your first integration from scratch. We pick up from wherever that integration stalled, connecting the labels, rates, and tracking events it generates to the order system, accounting, and support tools that still don't know about them.

What we build on top of ShipEngine

Label generation triggered by an order, not a person. An order hitting your system calls ShipEngine directly, picks a rate against rules you set, and creates the label, instead of someone keying the shipment into a form by hand because the original integration only ever covered the happy path.

Rate-shopping logic that reflects how you actually ship. ShipEngine returns every carrier's rate; deciding which one wins by weight, destination, or order value, and failing over to a second carrier when the first one's down, is logic that has to be written somewhere, and it's rarely finished on day one.

Tracking events that reach more than one screen. A status change from ShipEngine's tracking API updating your order system, your support desk, and a customer notification at the same time, instead of landing in only the one system someone originally wired it to.

Where this tends to show up

Order-to-label without a human step

An order placed anywhere in your stack calls ShipEngine, gets a label back, and the shipment record updates on its own, instead of waiting for someone to open a separate shipping tool.

Carrier failover built in from the start

If a primary carrier's API is down or a rate comes back unusually high, the order routes to a backup carrier automatically instead of sitting in a queue until someone notices.

Where does your ShipEngine setup still need a person?

Tell us which part of label creation, rate selection, or tracking sync still runs through someone's hands, and we'll look at whether it needs to.

Let's talk

Running ShipEngine under the hood and still patching the gaps by hand?

Tell us where your label logic, rate rules, or tracking sync still needs a person to step in, and we'll work out what's worth wiring directly into the API versus what's actually a different problem in your stack entirely. ShipEngine's just this page's example. The same question applies to any manual step still sitting in your shipping process.

Frequently Asked Questions

What is ShipEngine?+
A shipping API from Auctane (the same company behind ShipStation): multi-carrier rate quoting, label printing, address validation, and package tracking, built to be called from your own application rather than operated through a merchant dashboard.
Where do I find ShipEngine's API documentation?+
At ShipEngine's own developer docs site, which covers authentication, every endpoint (rates, labels, tracking, address validation), and sample requests in several languages. Worth reading before any integration work starts, since the gaps between what the docs describe and what your business actually needs are usually where the real build happens.
Is ShipEngine the same as ShipStation?+
No, though they're related. Both come from Auctane: ShipStation is the merchant-facing dashboard for managing orders and printing labels by hand or in bulk, while ShipEngine is the underlying API meant for developers building shipping logic directly into their own app or platform.
