Application Programming Interface

Application Programming Interface (API) provides standardized access to the features of a system without the need to understand the inner workings and functions of the system. Moreover, features and services that are accessible through the API are often referred to as being exposed VIA the API so that other applications can consume and accomplish advanced operations. Besides the features of the API can be called through the standardized techniques such as HTTP requests and other related methods of referencing external services. It offers a standardized way for source code modules or features to interact and may be exposed to the outside world through web services. Before included to one’s application, developers must test the APIs thoroughly to ensure that they enforce all security requirements.
