API-first development

Ship higher-quality applications faster by building your API before writing code.

1. Specification Phase

  • Create a new API Doc →
  • Write or import a new specification (optional)

2. Development phase

  • Create a mock server
    Doc →
  • Create documentation
  • Debug API

3. Testing phase

  • Explore the API
  • Write tests using Javascript
  • Verify test results in Collection Runner Doc →

4. Deployment phase

  • Integrate tests in build system through Newman
  • Deploy to production through your CI/CD pipeline
  • Set up Monitors to get alerts Doc →

Design and develop 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.

Develop and test simultaneously

Reduce dependencies by enabling teams to work in parallel.

Collaborate in Workspaces

Share your work in a dedicated workspace and invite your teammates to collaborate and give feedback in comments. With built-in version control, workspaces allow real-time collaboration and allow for faster feedback cycles.

Create mock servers

Create mock servers to simulate your API endpoints and communicate the expected behavior – all without having to set up a backend.

Generate documentation

Create documentation for individual requests and collections to help onboard API consumers more quickly.

Create reliable services with continuous integration and deployment

Easily integrate Postman into your CI/CD pipeline.

Automate with Newman

Easily increase test coverage and frequency by automating tests with Newman, Postman's command line tool.

Integrate with your existing pipeline

Seamlessly integrate your Postman instance with CI system like Jenkins or Travis to create your own CI/CD pipeline.

Prevent system breakage

Add a test suite as a build step into your CI/CD pipeline to ensure your APIs are compatible with any dependencies.

What is Postman?

Postman is an API platform for building and using APIs. Postman simplifies each step of the API lifecycle and streamlines collaboration so you can create better 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.


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


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.
