1Courier Ecommerce API

Public API for ecommerce integrations. Used by merchant-owned stores (Shopify primarily) to:

• Push fulfillment requests into 1Courier
• Track order status and driver position
• Query available service types and pricing

If you're building an internal tool, you want the internal backend API instead.

API surface

• Base path: /api (not /v3 — ecommerce uses a separate namespace)
• Production URL: https://api.v3.1courier.com/api
• Auth: customer-scoped API key via X-Api-Key header. Request keys from your 1Courier account rep.
• Transport: HTTPS only. CORS is open (*) — you can call from a browser-based Shopify app.
