Key Points
- Postman has a special client for GraphQL requests called the GraphQL client.
- The GraphQL client has features that allow you to create and execute GraphQL requests more efficiently.
- It automatically fetches the schema of a GraphQL API and uses introspection to show you the available data fields.
- You can explore the data fields of a GraphQL API and construct queries by selecting fields or entering code in an editor.
Prerequisites
Steps
Step 1. Create a new request
Step 2. Select a new Client
