Eliminate dependencies and reduce time to production by having front-end and back-end teams work in parallel.
Postman schema support gives you visibility into your API specifications and structure.
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.
Track and communicate changes to the API design by editing and versioning schemas in one central location. No more having to switch between tools.
Rely on your schema as a source of truth for API design and development and ensure all teams are working toward the same goal.
See how your API will run – even before it's in production. Mock servers simplify API design and planning, support split-stack development, and help you ensure that your API will run the way it's supposed to in 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.
View API responses with the applications and services waiting to use it before and during development.
Get better visibility into errors so you can debug more quickly.
Write test suites so that teams can debug together
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.
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.
Download the Postman app and send your first request within minutes. Postman is free to download and use for teams of any size.
Make any kind of API call—REST, SOAP, or just plain HTTP—and easily inspect even the largest responses. Postman also has built-in support for popular data formats, including OpenAPI, GraphQL, and RAML.
We continually make improvements and add new features based on feedback from our community of over 8 million users. Get help from Postman experts and your peers on the community forum.
