Design and Develop Applications Faster with Schema Support
Broad Schema Support
Use the API specification format of your choice in Postman. Write, edit, or import schema formats including RAML, WADL, OpenAPI, and GraphQL. Then generate collections directly from the schema.
Edit and Version Schema
Track and communicate changes to the API design by editing and versioning schemas in one central location. No more having to switch between tools.
Maintain a Single Source of Truth
Rely on your schema as a source of truth for API design and development and ensure all teams are working toward the same goal.
Simulate Your API Endpoints with Mock Servers
Reduce time to production
Postman mocks support split-stack development so front-end and back-end developers can work in parallel and view responses without spinning up a back end.
Communicate your API's expected behavior
View API responses with the applications and services waiting to use it before and during development.
Catch and fix bugs early
Get better visibility into errors so you can debug more quickly.
Ensure High Quality APIs by Writing and Running Test Suites
Create Test Suites
No Code Necessary
Build and run test suites without having to write any code with Postman's built-in test scripts. Add onto them with assertions specific to your endpoint's expected response.
Run the Tests
Use the collection runner in the Postman app to test a collection and view the results in real time. Or use Newman to view test results in the terminal.
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.
Support and Community
We continually make improvements and add new features based on feedback from our community of over 13 million users—who can also help you get the most out of Postman on our community forum.
Twitter Grows Its Developer Ecosystem with Postman
"With Postman as our prototype testing platform, we were able to reduce our feature development cycle from months to a three week sprint cycle."
Chloe Kaliman, Senior Partner Engineer, Developer Relations, Twitter
Yodlee uses Postman to manage all the data required to build an app
"I know developers love to test first and read later, so my goal is to help developers make test calls within five minutes and become successful. They want to get up and running right away"
Vu Nguyen, Envestnet | Yodlee
Postman Collections, Newman, and test scripts power a wide range of Paylocity's QA use cases.
"Postman enables me to quickly build out a test automation and hit the ground running. I’d say 90% of my API test cases are run on Postman."
Annamalai Viswanathan, QA Engineer, Paylocity
