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.
