1. Get your API

  • Import API specification
  • Import a Postman Collection Doc →
  • Import curl commands

2. Explore the API

  • Craft API requests and validate responses
  • Use dynamic dummy data
  • Create requests with pre-requests scripts
  • Chain requests to create test scenarios

3. Invite your to team to explore together

  • Create collections for easy knowledge transfer
  • Invite teammates to workspace
  • Collaborate with comments Doc →

Import an API and send requests

Postman makes it easy to work with APIs and perform exploratory testing.

Exploratory Testing Example Request

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 in seconds from

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

Parameterize your requests

Use our built-in library of dynamic variables to generate dynamic dummy data for testing multiple iterations of the same request with different values.

Inspect responses of any size

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

Exploratory testing made easy

Use the Postman Sandbox to write tests that you can share with teammates.

Exploratory Testing with Postman Sandbox

Use scripts to send asynchronous requests

Use pre-request scripts to execute logic in the background when sending multiple requests. Instead of waiting for a call to complete and blocking further requests, designate a callback function and you'll be notified when it's done.

Chain requests to create test scenarios

Chain requests to create test suites by using pre-request and test scripts to parse information from the response body and save it as a variable used in additional requests.

Easily share your findings

Document your discoveries in a collection and communicate them to developers by sharing the collection to a team workspace.

What is Postman?

Postman is an API platform for building and using APIs. Postman simplifies each step of the API lifecycle and streamlines collaboration so you can create better APIs—faster.

API Tools

A comprehensive set of tools that help accelerate the API Lifecycle—from design, testing, documentation, and mocking to discovery.

API Repository

Easily store, iterate and collaborate around all your API artifacts on one central platform used across teams.


Organize your API work and collaborate with teammates across your organization or stakeholders across the world.


Improve the quality of APIs with governance rules that ensure APIs are designed, built, tested, and distributed meeting organizational standards.

Case studies

See a wide selection of detailed use cases from nearly every industry on the Postman case studies page.
