The Shopify Storefront API is designed to provide access to Shopify-generated data of customers, nodes, and shops. Customer information includes items like shipping addresses and display names, while the nodes data interface concerns checkouts, collections, and orders applications. Shop information accessible through the Storefront API includes billing addresses and currency codes. Its integration in ecommerce applications allows users to perform various tasks including checkout and shopping cart customizations, single product or multiproduct data acquisition for website displays, and creation of new or modification of existing customer data. The API is currently a beta release and can only be accessed through a GraphQL endpoint.
