ShipEngine provides shipping infrastructure APIs for labels, rates, tracking, addresses, carriers, shipments, warehouses, and related logistics workflows. Its developer documentation notes the product is being rebranded as ShipStation API while existing endpoints remain the same.
ShipEngine exposes one authenticated REST API at `https://api.shipengine.com`, documented with an OpenAPI spec and authenticated by an API key in the `API-Key` header.
