GraphQL query language allows the client to specify the structure of the requested data, and returns data from the server using the same structure. Such design ensures that only required data is retrieved, thus improving query efficiency.

Create a GraphQL query

You can create GraphQL queries in two ways:

  • add a new data source and then create a query

  • create a query directly

Note that without creating a new data source, the GraphQL data source is not stored in your Data Sources and thus cannot be accessed to build other queries.

Create a query with a new data source

Follow the steps to add a new GraphQL data source first and then create a query.

  1. Connect GraphQL API to access to.

  2. In the query editor, click + New.

  3. Select the added API in Data source.

  4. Write a query.

  5. Click ▶ Run.

For details about using GraphQL, reference Introduction to GraphQL.

The following GraphQL query searches the latest 20 closed issues in the repository octocat/Hello-World, and returns the title, URL, and the first 5 labels of each issue.

Create a query with predefined data source

Follow the steps to create a GraphQL query directly.

  1. In the query editor, click + New.

  2. Select GraphQL Query in Data sources. Lowcoder offers this built-in plain data source so that you can quickly create GraphQL queries without adding a new data source first.
