API is the acronym for Application Programming Interface, which is a software intermediary that allows two applications to talk to each other.
Each time you use an app like Facebook, send an instant message, or check the weather on your phone, you’re using an API.
Postman is an API ((Application Programming Interface)) platform for building, modify and using APIs. Almost any functionality that could be needed by any developer is encapsulated in this tool.
Postman simplifies each step of the API lifecycle and streamlines collaboration so you can create better APIs faster.
It is used by over 5 million developers every month to make their API development easy and simple.
It has the ability to make various types of HTTP requests(GET, POST, PUT, PATCH), saving environments for later use, converting the API to code for various languages(like JavaScript, Python).
Postman is available as a native app (built on Electron) for all major operating systems, including macOS, Linux, and Windows.
It also started as a Chrome browser extension and quickly became one of the most widely used API tools by developers all over the world.
