Application development

Accelerate application development with Postman—eliminate dependencies and reduce time to production by having frontend and backend teams work in parallel.

  • Integrate API test with build system

Design and develop applications faster with schema support

Postman schema support gives you visibility into your API specifications and structure.

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

See how your API will run even before it's in production. Mock servers simplify API design and planning, support split-stack application development, and help you ensure that your API will run the way it's supposed to in production.

Mock Servers Support Split-Stack Application Development

  • 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

Write test suites so that teams can debug together.

Support Application Development with Test Suites

  • Create test suites

    Write custom test suites in JavaScript in the Postman Sandbox for each request. Use Postman's PM API to assert a set of predefined rules for better and cleaner tests.

  • 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.

What is Postman?

Postman is an all-in-one API platform for building and working with APIs. It takes the pain out of every stage of the API lifecycle—from designing and testing to delivery and monitoring. Built for teams, Postman makes it easy to collaborate, stay organized, and build secure, reliable APIs faster.

API Tools

A comprehensive set of tools that help accelerate the API Lifecycle—from design, testing, documentation, and mocking to discovery.

API Repository

Easily store, iterate and collaborate around all your API artifacts on one central platform used across teams.

Workspaces

Organize your API work and collaborate with teammates across your organization or stakeholders across the world.

Governance

Improve the quality of APIs with governance rules that ensure APIs are designed, built, tested, and distributed meeting organizational standards.

Case studies

See a wide selection of detailed use cases from nearly every industry on the Postman case studies page.
