Postman API Client

What is Postman API Client?

Send requests, inspect the response and debug easily.

Send requests and view responses

Create and save REST, SOAP, and GraphQL queries directly from Postman.

Define complex requests

Submit any kind 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 plain text data
• multipart / form-data - To send large amounts of binary data or text containing non-ASCII characters
• Raw body editing - To send data without any encoding
• Binary data - To send image, audio, video, or text files

Starts working in seconds

Instead of manually creating calls to send over the command line, all you need is a collection. Import a collection directly or generate one with a click on:

• An API scheme in RAML, WADL, OpenAPI, or GraphQL format,
• A data file containing the cURL commands

Inspect responses

See the status code, time, and size of the response. Postman's automatic language detection, link highlighting and syntax, searching, and text formatting make it easy to inspect the response body.

Manage authentication

Postman allows you to access APIs regardless of the authentication protocol that supports it.

Support for multiple protocols

Postman provides integrated support authentication protocols, including OAuth 2.0, AWS Signature, Hawk Authentication.

Manage cookies

Capture the cookies returned by the server when making a request and save them for reuse on later requests. You can also create custom domains and add cookies to them.

Manage certificates

View and define SSL certificates on a per-domain basis. After a client certificate is added, it is automatically sent with any future request for that domain sent over HTTPS. Postman supports:

• SSL certificate validation
• Custom root CA certificate support
• Customer certificate support

Built-in support for variables

Keep your code and request DRY by reusing values in multiple locations with variables.

Create variables in multiple scopes

Store values at the desktop level ("global"), at the environment, and at the collection level. Add variables to URL, URL parameters, headers, authorization, request body, and header presets directly in Postman.

Make requests quickly for different environments

Use environments to easily switch between different settings without changing your requests. Simply select the appropriate environment to update your variable values.

Use session variables to keep information secure

Manage sensitive data, such as API keys, by storing it in session variables that remain local on your machine and are never synchronized with your team.

More than just an API client

Postman has features that make it a powerful tool for API exploration and development

Generate code snippets

Generate code snippets of your requests in a variety of frameworks and languages that you can use to make the same requests as your own application.

Track request history

Postman stores all the requests you submit on the History tab, allowing you to experience variations of requests quickly, without wasting time creating a request from scratch.

Write tests on the postman's sandbox

Use test and pre-request scripts to add dynamic behavior to requests and collections. This allows you to write test suites, create requests that can contain dynamic parameters, pass data between requests, and more.
