Shopify Storefront API – The backend behind the custom storefront SDKs

Using GraphQL, a flexible and standards based API specification, the Storefront API allows you to ask for exactly what you need and nothing more. You can efficiently get all the data you need in a single request with predictable responses. The Storefront API provides a schema with a self-describing type-system which gives you clear and helpful errors, data-type guarantees, and powerful developer tools.
