 data we are sending to the server

 format you want to get in the response like (json or xml)

what is request API

What is an API Request?

If you specialize in apps or software development,
you must have come across the term API.
This is the short form for Application Programming Interface,
and it technically refers to a robust set of procedures,
tools, and protocols that permit the interaction between web applications.
It is an intermediary that delivers a client’s request to the server and then returns a response to the client.

APIs help software developers to streamline and shorten the application building process by eliminating frequently repeated program development processes.
In short, they help you not to keep reinventing the wheel every time you are using the same procedure to build applications.
With APIs, developers can omit some of the simple programming steps,
and thus save time and increase productivity.
However, for programmers to use APIs, they must know how to make API requests.
