Optimized One-Page Checkout is BigCommerce’s default checkout and order confirmation page.

The Storefront Checkout API surfaces the business logic of the backend ecommerce application — retrieving customer information, fetching available shipping methods, and calculating discounts and sales tax.

Headless Checkout

BigCommerce surfaces APIs that cover the full checkout process end-to-end, which means that you can build a fully custom checkout either on top of the native storefront, or on a remote platform.

Headless means that the front-end presentation layer has been decoupled from the backend platform that powers it

Checkout JS SDK

Checkout JS SDK: https://github.com/bigcommerce/checkout-sdk-js
methods: https://github.com/bigcommerce/checkout-sdk-js/blob/master/docs/classes/checkoutservice.md

Checkout pages built with the SDK are considered headless because you’re replacing the native presentation layer with one that’s custom-built on another framework. The Checkout SDK can also provide a checkout solution for remote headless storefronts, if you redirect back to the BigCommerce domain for the checkout step.

Embedded Checkout

Embedded checkout is a great solution for a remote headless storefront, because shoppers can complete their purchase in-context, without being redirected to a BigCommerce domain.
