What is Microsoft Fabric API for GraphQL?

  • Article

Note

Microsoft Fabric API for GraphQL is in preview.

Microsoft Fabric API for GraphQL is a data access layer that enables quick and efficient querying of multiple data sources with a widely adopted and familiar API technology. The API allows you to abstract the specifics of backend data sources so you can concentrate on your application's logic, and provide all the data a client needs in a single call. GraphQL uses a simple query language and easily manipulated result sets, which minimizes the time it takes for applications to access your data in Fabric.

Expose data through the API for GraphQL

Exposing data sources to a GraphQL item in Microsoft Fabric is quick and easy. Select the data source you would like to expose and then indicate which objects within that data source you want to present through the API. Optionally, define any relationships between the fields that you choose. After you complete these steps, your API endpoint is ready to accept queries.
