Exploratory Testing

Explore APIs, send requests, and inspect responses with Postman's exploratory testing.
Exploratory Testing with sending three kinds of data. Illustration.

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 Made Easy

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.

Case Studies

UCSF reduces QA time by sharing in Postman

"It's awesome being able to set the Postman environments so everyone shares the credentials. That’s been a godsend for us."

Todd Parsnick, Technical Manager, UCSF

Yodlee uses Postman to manage their numerous data sources

"Postman is my cheatcode—I add an endpoint and it spits out all the information I need in seconds."

Vu Nguyen, Envestnet | Yodlee

Lucid engineers troubleshoot their APIs with Postman tests

"With Postman, I don't have to be conservative or cautious to the point of impedance when it comes to making changes; I can iterate rapidly and with confidence."
