What is Postman?

It is an API platform to build and use APIs. You can create better or faster APIs with the help of an API repository, tools, intelligence, workspace, and integrations. It is built on open-source technologies.

• API repository – Using the central platform you can easily store, catalog, and collaborate all your API-related stuff like test cases, specifications, documentation, etc.
• Tools – It provides various sets of API tools to accelerate the API lifecycle like design, testing, mocking, documentation, etc.
• Intelligence – It provides an advanced level of intelligence and insights about the API operations alerts, search, security warnings, reporting, etc.
• Workspace – It helps you to organize your API work and collaborate across the world. There are three different workspaces – personal, team and public.
• Integrations – It is a most important tool in the software development pipeline to go with API-first practices. You can integrate postman into the code repositories, CI/CD pipeline, you can build your integrations using the postman API, etc.
