Api-Design

HTTP status codes are a contract consumed by clients, load balancers, monitoring, and caches. When you return 200 OK for partial failures, every one of these systems is blind.

SAP Commerce OCC promises a stateless REST API for headless commerce. Underneath, every request hydrates an HTTP session and routes through the same stateful facades built for the JSP storefront. The API is stateless in contract but stateful in implementation.
