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 API is also used as a ‘user interface’(UI) through which applications, devices can exchange data with each other.
