Postman GraphQL Client
Send requests, inspect responses, and easily debug GraphQL APIs.Download the App
Send Requests and View Responses
Use Postman as a GraphQL client to create and execute queries. (Postman also works with REST and SOAP.)
Define complex requests
Send any type of request in Postman. Create and save custom methods and send requests with the following body types:
URL-encoded—The default content type for sending simple text data
Multipart/form-data—For sending large quantities of binary data or text containing non-ASCII characters
Raw body editing—For sending data without any encoding
Binary data—For sending image, audio, video, or text files
Get up and running in seconds
Instead of creating calls manually to send over the command line, all you need is a Postman Collection. Import a collection directly or generate one with one click from:
An API schema in the RAML, WADL, OpenAPI, or GraphQL format
A data file containing the cURL commands
View the status code, response time, and response size. Postman's automatic language detection, link and syntax highlighting, search, and text formatting make it easy to inspect the response body.
Visualize Your Data
Easily turn API data into charts and graphs with Postman Visualizer.
Utilize powerful, simple visualizations
Go beyond parsing API JSON or XML responses. API consumers can get more from API data by taking advantage of prebuilt charts and graphs.
Build your own
Share with your team
Visualizations can easily be shared with others utilizing Postman Collections.
Built-In Support for Variables
Keep your code and requests DRY by reusing values in multiple places with variables.
Create variables in multiple scopes
Store values at the workspace level ("globals"), at the environment, and at the collection level. Add variables to the URL, URL parameters, headers, authorization, request body and header presets directly in Postman.
Quickly make requests to different environments
Use environments to easily switch between different setups without changing your requests. Just select the appropriate environment to update your variable values.
Use session variables to keep information secure
Manage sensitive data like API keys by storing them in session variables that remain local to your machine and are never synced to your team.
Postman lets you access APIs no matter the authentication protocol backing it.
Support for multiple protocols
Postman provides built-in support authentication protocols, including OAuth 2.0, AWS Signature, Hawk Authentication, and more.
Capture cookies returned by the server when making a request and save them for reuse in later requests. You can also create custom domains and add cookies to them.
View and set SSL certificates on a per domain basis. Once a client certificate has been added, it will automatically be sent with any future request to that domain sent over HTTPS. Postman supports:
SSL certificate validation
Custom root CA Certificate support
Client certificate support
More than Just a GraphQL Client
Postman is packed with features that make it a powerful tool for API exploration and development.
Generate code snippets
Generate code snippets from your requests in a variety of frameworks and languages that you can use to make the same requests from your own application.
Keep track of request history
Postman stores all requests you send in the "History" tab, allowing you to experiment with variations of requests quickly without wasting time building a request from scratch.
Write tests in the Postman Sandbox
Use test and pre-request scripts to add dynamic behavior to requests and collections. This allows you to write test suites, build requests that can contain dynamic parameters, pass data between requests, and more.
Test and Debug All Your APIs
Discover how Postman enables API-first development, automated testing, and developer onboarding.
Release reliable services by building your API before deploying code.
Eliminate dependencies and reduce time to production by having front-end and back-end teams work in parallel.
Automate manual tests and integrate them into your CI/CD pipeline to ensure that any code changes won't break the API in production.
Explore the API by sending it different kinds of data to see what values are returned.
Quickly get consumers up to speed on what your API can do and how it works.
Publish API documentation to help internal and external consumers adopt your APIs.
