Storefront REST APIs

Client-side REST APIs designed for use in a browser or storefront context. These APIs let you interact with carts, checkouts, and customer data directly from storefront JavaScript without a server-side proxy.

Authentication

Storefront REST APIs use same-origin CORS authentication — no token is required when requests are made from the store’s native storefront. Requests must originate from the storefront domain.

For server-side or headless usage, consider the GraphQL Storefront API, which offers broader capabilities with bearer token authentication.
