An Application Program Interface (API) is code that
allows two software programs to communicate with each other.

Where it is used?
An example, you are
buying an item in on-line through your credit card. You will provide credit card
details and submit your information. It will tell you whether your information
is correct or not. To provide these results, there is lot of things in the back end.
The application will
send your credit card details to a remote application which will validate your
information and send the result back your application. In this process you are
using API.
I think hope it
helps for the beginners who doesn't understand what API is.
