What is REST API?
A REST API (Representational State Transfer Application Programming Interface) allows software systems to communicate over HTTP using standard methods (GET, POST, PUT, DELETE) to exchange data.
How REST APIs Work
A REST API exposes endpoints (URLs) that return or accept data (usually JSON). GET /api/customers returns customer list. POST /api/sales_order creates a new order. The client sends HTTP requests with headers (authentication, content type) and receives JSON responses. REST APIs are stateless — each request is self-contained.
ERPNext REST API
ERPNext exposes a complete REST API at /api/resource/[DocType] for all DocTypes. Authenticate with API Key + Secret or session token. Example: GET /api/resource/Sales%20Order?filters=[["status","=","Open"]] returns all open sales orders. Infonoxe builds integrations connecting ERPNext to eCommerce, payment gateways, and third-party apps via REST API.
