What is API ?


Abbreviation of application program interface, a set of routines, protocols, and tools for building software applications. A good API makes it easier to develop a program by providing all the building blocks. A programmer then puts the blocks together.

Most operating environments, such as MS-Windows, provide an API so that programmers can write applications consistent with the operating environment. Although APIs are designed for programmers, they are ultimately good for users because they guarantee that all programs using a common API will have similar interfaces. This makes it easier for users to learn new programs.


Now a day most of organization provide the API for retrieve information from their global database. So social network sites provide the API for retrive friend list,news feed,current activities etc.
Example Facebook API,Tweeter API,Linked in API etc. Other organization also provide their API for retrieve valuable data from the global database. Ex -Google API for MAP,Contact,Translation and many more .So API make easier to develop a Application as per their requirement.
