What is API?
API (Application Programming Interface) is the powerful way programmers and certain applications communicate. APIs are designed to fulfill a certain purpose such as communicating and sending data from one program to another. An API interface allows two applications to meet and interact with each other.
How Does API Works?
The API is necessary every time application data is going to be accessed. You must use a very precise language as the application only allows you to access certain amounts of data. The language is unique to each particular application. The API is the middleman between the application and the programmer. It accepts the request for data and retrieves it from the application if it is allowed.
An Example of API in Action
Using a keyword search tool is a good example of an API in action. The tool must access Google and Bing’s search API to retrieve information on the best keywords your business should focus on targeting. By using the precise language to request from the application, the tool is able to retrieve the allowed information from the search engines.
