Postman is the perfect app for exploring API's
Explore APIs, send requests, and inspect responses with Postman's exploratory testing.
Import an API and Send Requests
Postman makes it easy to work with APIs and perform exploratory testing. 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.
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 notifi ed 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.
It's Free and Easy to Start
Just download the Postman App and send your first request in minutes. Postman is free to download and use for teams of any size.
Wide support for all APIs and Schemas
Make any kind of API call—REST, SOAP, or plain HTTP—and easily inspect even the largest responses. Postman also has built-in support for popular data formats such as OpenAPI GraphQL, and RAML.
Customize Postman for your needs with the Postman API. Integrate test suites into your preferred CI/CD service with Newman , our command line collection runner.
