Application Development

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

Design and Develop Applications Faster with Schema Support

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

Case Studies

SynapseFI relies on the Postman Sandbox to onboard consumers

"I’ve never been in a company where both engineers and non-engineers use the same tool in the same way."

Asya Bradley, VP of Business Development and Sales, SynapseFI

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
