In the current scenario, building any application sans application programming interface (APIs) will not suffice user requirements. Corporate software developers with foresight include APIs in their applications, as they expect their apps to be robust and interacting effectively with other applications.

Similar to the dependence on peers for performing various day-to-day activities in the real world scenario, the virtual world too necessitates assistance from contemporary software for the functioning of regular operations. Along with time, this interdependence of different applications will grow. Custom API development is one great way to enrich a website with useful data and processes without having to write redundant lines of code. Application Programming Interface (API) forms the basic set of functionalities required for creating software applications, and enables interaction between apps, without any interruptions. Operating Systems are facilitated by APIs in performing basic functions and hence, APIs are considered, by most of the applications, to be the essential platform for requesting service from other software programs. They provide the means to request program services and grant access to open an application.
