REST API basics

We built a complete REST e-commerce API that lets you manage your data the way you need. It uses standard HTTP features — authentication, verbs, and response codes — to stay predictable and easy to use.

Essentials

Base URL	https://app.snipcart.com/api
Format	JSON only — always send the Accept: application/json header on every request.
Authentication	HTTP Basic with a secret API key (key as username, empty password). See Authentication.
Errors	Standard HTTP status codes, with a JSON error body on 4xx. See Errors.
Evolving payloads	Snipcart may add new fields to API responses at any time, without notice or a new version. Existing fields are not renamed or removed, so ignore fields you don't recognize rather than failing on them (e.g., avoid strict schema validation that rejects unknown properties).

A first request

curl -H "Accept: application/json" \
  https://app.snipcart.com/api/orders \
  -u {YOUR_SECRET_API_KEY}:
