Use cases
Discover how Postman enables API-first development, automated testing, and developer onboarding.
API-first development
Release reliable services by building your API before deploying code.
Automated testing
Automate manual tests and integrate them into your CI/CD pipeline to ensure that any code changes won't break the API in production.
Developer onboarding
Quickly get consumers up to speed on what your API can do and how it works.
Application development
Eliminate dependencies and reduce time to production by having front-end and back-end teams work in parallel.
Exploratory testing
Explore the API by sending it different kinds of data to see what values are returned.
Developer portals
Publish API documentation to help internal and external consumers adopt your APIs.
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.
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.
