Application Programming Interface (API) is indispensable to any web solution, software module, plugin, web application, or web design as it lays down the protocols / standards to access a web-based app. Whether you want to create a web-based software application, or a web-tool, API plays a critical role in the success of your business endeavours, as it is an integral component that facilitates reliable interaction between computer hardware, databases, and software components.
Importance of an API can be gauged from the fact that almost all powerful apps these days are powered by highly specialized APIs, each developed to execute a specific function.
