How Does The Application Programme Interface Work?

What is it?

The Application Program Interface or API is intermediate support that allows the conversion and connection of the source messages to the receiver. For Example, if we talk about a Bank, where you can withdraw or deposit your money, you can do it easily over there. But now the question arises who would take you to your account data to perform your transaction? It is the Cashier or the Person appointed in the Bank that allows you to do your job. This is exactly what API does. It becomes an intermediary source to connect two people who need each other to compete for a task. It is based on an online server mechanism that sends and receives signals or messages.

  • It helps us by never exposing our data to the server online.
  • They are easily understood.
  • They are developer and user friendly.
  • They are broadly accepted.
  • They are treated as products rather than just codes.
  • They are documented and versioned specifically to be customer/ user friendly.
  • As they are present in standard forms, they can have high security and Governing properties.
  • They can be monitored, and their performance can be balanced.


There is a public or open Application Programme Interface, but it is not free of cost. There are many APIs out over there, but what is important is associated with the platforms that get these interface swiftly and easily to interact with the source and the receiver needs.  For example, Google and Facebook APIs are highly efficient and allows you to access their marketing and social graph tools along with maps and translators etc. The API formulation takes place through the HOW and WHAT process. Mostly, APIs that perform similar actions behave in the same manner.
