  title: Swell Backend Orders API
  description: 'Swell is a composable headless commerce platform exposing a server-side Backend API for managing products, orders, customers, and related resources. The HTTP API is organized around REST principles and is authenticated using your Store ID and a Secret Key issued from the Swell Developer dashboard. Note: Swell''s official SDKs use a proprietary wire protocol on port 8443 for performance; this OpenAPI documents the HTTP-equivalent REST shape used by the Backend API.'
