An application programming interface (API) is a messenger that processes requests and ensures seamless functioning of enterprise systems. API enables interaction between data, applications, and devices. It delivers data and facilitates connectivity between devices and programs.
APIs ensure a seamless communication between various applications. But, it is so done by exposing limited amount of a program’s internal functions. For example, an app like Zomato is enabled by API to show the restaurant locations on Google Maps. So, in other words, API integration eases businesses and benefits consumers.
