What is API?

It is a kind of software that works to connect two programs together. It is a set of codes by which accessing the Internet is made easy. If you want to use data or functions of any other application in your app, then for this you have to use API. By this, the code does not have to be written again and again, which makes computer programming very simple. For example, if you go to a website, there are 2 options to log in to that website.

If we open a website, then with the help of these two options, we can log in to it. Both these companies are very large, so for other small websites, the facility of logging in with Google and Facebook is given so that they can be logged in with one click. So our details are taken to login page through API itself.
