Postman GraphQL client

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

Inspect Responses

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

Developers can harness HTML5, JavaScript, and CSS or bring in many of the available charting and graphing libraries to create rich visualizations.

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.

Manage authentication

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.

Manage cookies

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.

Manage Certificates

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.
