The full form of API in computer is APPLICATION PROGRAMMING INTERFACE.
What does API Stand For?
API (Application programming interface) is a software which acts as an intermediary between two applications and aids in the communication between them.
Each time you are using an application for example Spotify, you are interacting with its API. In this case, you are interacting with Spotify’s API to find the song you like.
How does an API work?
Whenever an application is used in a phone, the app gets connected to the internet and sends information to the server. Then the data is retrieved, interpreted and the server takes important actions and sends the data back to the phone.
The application then re evaluates the data and delivers it to you in a readable way. This is how an API works by receiving request, working on it and responding through the data necessary for the service.
The API is also used as a ‘user interface’(UI) through which applications, devices can exchange data with each other.
For example, when you click on the play button in YouTube to start the video, a request is sent to the server to access the video and then by responding to the data, the video starts to play.
