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.
API can also be defined as an online programming interface of the organization. It allows applications to communicate with backend systems.
An application programming interface creates a channel for the company to sell its products and services online. API enables access of services by adding codes to applications. It further enhances connectivity and bolsters functionality.
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.
