BigCommerce

BigCommerce is a hosted commerce platform used by mid-market and enterprise merchants who want a storefront and checkout without running the infrastructure themselves.

Its APIs expose the storefront and checkout events that matter for acquisition — cart, checkout and order — which is what makes a clean server-side feed possible.

BigCommerce hosts the storefront and checkout and exposes them through a REST Management API plus a webhook system covering carts, orders and customers. Stores can run headless, with BigCommerce serving as the commerce engine behind a front end you control. Checkout is hosted, which keeps PCI scope down but also limits what a script running in the page can observe at the moment of purchase. The order object — totals, line items, customer — is available server-side regardless of how the storefront was built.

BigCommerce’s hosted checkout protects you from PCI scope and hides the purchase from browser-side scripts. Upstack reads the order server-side instead, so the limitation stops mattering, then resolves the customer against the device graph before forwarding. Multi-storefront accounts resolve against one graph rather than per store, so a shopper who buys from two of your regions is one customer everywhere downstream.
