GraphQL Admin API
The GraphQL Admin API lets you build apps and other integrations for the Shopify admin using GraphQL. With the API, you can create apps that offer functionality at every stage of a store's operation, including shipping, fulfillment and product management.
The GraphQL Admin API is a GraphQL-based alternative to the REST-based Admin API, and makes the functionality of the Shopify admin available at a single GraphQL endpoint. The full set of supported types can be found in the GraphQL Admin API reference.
