14. Belajar API (Application Programming Interface) Postman Bahasa Indonesia

Postman is an Application Programming Interface (API) testing tool. API acts like an
interface between a couple of applications and establishes a connection between them.
Thus, an API is a collection of agreements, functions, and tools that an application can
provide to its users for successful communication with another application. We require
an API whenever we access an application like checking news over the phone, Facebook,
and so on.
Postman was designed in the year 2012 by software developer and entrepreneur
Abhinav Asthana to make API development and testing straightforward. It is a tool for
testing the software of an API. It can be used to design, document, verify, create, and
change APIs.
Postman has the feature of sending and observing the Hypertext Transfer Protocol
(HTTP) requests and responses. It has a graphical user interface (GUI) and can be used
in platforms like Linux, Windows and Mac. It can build multiple HTTP requests – POST,
PUT, GET, PATCH and translate them to code.
