How to hit the ShipEngine API

ShipEngine at https://api.shipengine.com/v1 connects to many carriers — UPS, FedEx, USPS, DHL — through one API.

Authentication

Copy a key from the ShipEngine dashboard (sandbox keys start with TEST_) and send it as the API-Key header. In the examples it's written {{SHIPENGINE_API_KEY}}.
