GraphQL

For client-side applications, GraphQL provides benefits in terms of performance, state management, maintainability, and user experience. At commercetools, the main method of data fetching used by the Merchant Center is using the GraphQL API.

The Merchant Center API Gateway exposes a /graphql endpoint, in addition to the proxy endpoints. This endpoint should also be considered a proxy endpoint, as it connects to different underlying GraphQL APIs.

Available GraphQL schemas

The following GraphQL schemas are available:

  • commercetools platform projects: this is the official GraphQL API for the commercetools platform.
  • commercetools platform administration: this GraphQL API handles tasks like managing projects and organizations.
  • Merchant Center users: this GraphQL API handles tasks like authentication, users, etc.
  • Merchant Center settings: this GraphQL API handles tasks like UI settings, Custom Applications, etc.

Request format

Requests to the /graphql endpoint require one or more HTTP headers, to determine the proxy target.

  • X-Graphql-Target (required): Specifies the GraphQL server to connect to, either one of:

    • ctp: to target the commercetools platform projects API.
    • administration: to target the commercetools platform administration API.
    • mc: to target the Merchant Center users API.
    • settings: to target the Merchant Center settings API.

    These values are available in the @commercetools-frontend/constants package as GRAPHQL_TARGETS variable. When sending queries from React components, you need to pass the value as a variables.target. For an example of a fully constructed request, see Data fetching.

  • X-Project-Key (optional): Specifies the project key to be used by the targeted GraphQL server. This value is not always required (depending on the query), but it's recommended to always send it whenever possible.
