What the Store API actually exposes
Shopware's Store API exposes product, category, cart, and checkout data over a REST/GraphQL-style interface, decoupled from the Twig storefront entirely. A headless frontend calls this API directly, while Shopware Admin stays the backend of record for catalog, inventory, and orders.
That split means checkout logic, pricing rules, and order processing still run inside Shopware — the frontend is a presentation layer, not a reimplementation of commerce logic. Getting that boundary right is most of what makes a headless build maintainable long-term.
