Use the Postman API Platform to send requests, inspect responses, and easily debug GraphQL APIs. ## GraphQL client Build, debug, and collaborate on GraphQL APIs in a unified platform. --- #### Build GraphQL queries effortlessly with the query builder - View documentation directly alongside the visual query builder, which uses introspection to automatically load your GraphQL schema - Assemble code-ready queries, mutations, and subscriptions by selecting fields in the query builder - Keep your queries clean with helpful errors that simplify the manual query writing process ## How does the Postman GraphQL client work? The Postman GraphQL client, which expands on Postman's core API client functionality, offers a powerful and efficient way to work with GraphQL APIs. With Postman's GraphQL client, you can: --- #### Explore and import GraphQL schemas easily - Automatically introspect a GraphQL schema by entering the API's URL - Import a schema from an API definition or a local file - Easily browse the available data fields, as well as their required arguments and descriptions --- #### View and analyze GraphQL responses - Streamline your workflow by viewing the schema explorer, query builder, and response side-by-side - View subscription responses in a filterable stream, which can be expanded for deeper analysis - Use the search input to look for elements in a single response—or to find specific responses within a stream --- #### Leverage Postman's core API client features - Define authentication details using a variety of authentication protocols—including OAuth 2.0, JWT, and AWS Signature - Collaborate on GraphQL APIs in private, partner, or public workspaces, which include support for commenting and version control - Define variables at the global, collection, session, and environment levels, and use them in any request's URL, headers, and body --- ### What other protocols does the Postman API client support? Postman is more than just an [API client](/api-platform/api-client/)—it's an API platform that simplifies each step of the API lifecycle and enables teams around the world to collaborate more efficiently. In addition to gRPC, the Postman API client also supports: ### REST The Postman API client enables users of all experience levels to call, test, and debug any REST API in a matter of minutes. [Learn more](/product/rest-client/) ### gRPC Postman users can easily invoke unary, client-streaming, server-streaming, and bi-directional streaming gRPC methods—and leverage autocomplete hints when composing a gRPC message. [Learn more](/product/grpc-client/) ### SOAP Postman's SOAP client makes it easy to compose request bodies in XML—and it automatically adds the application/xml content type header to the request, as well. [Learn more](/product/soap-client/) ### WebSocket Postman streamlines the process of connecting to a WebSocket API server—and enables users to compose and send WebSocket messages, search through the message stream, and listen for specific events.

GraphQL is an open source query language for APIs that enables developers to interact with a single endpoint and specify the exact data they need. There are three GraphQL operation types: queries, mutations, and subscriptions. Queries retrieve data, mutations create and manipulate data, and subscriptions fetch live data over a persistent connection. A GraphQL client streamlines developer workflows by making it easier to assemble and debug any GraphQL operation—while providing full visibility into the API's available data. --- ### Get started today Join the millions of developers who are already developing their APIs faster and better with Postman.
