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

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.
