In this blog, you’ll get to know about what APIs are, why developers are using them.
What is API?
API is an acronym for Application Programming Interface. API contains functions, Protocols, and tools that help developers add complex functionalities in their applications without writing a complete code.
What does API do?
APIs allow the user to access specific functionalities by using a simple syntax. Using APIs is a proper way of requesting services from any server, operating system, or other application applications. Some of the APIs are built-in browsers. Also, third party APIs are used in various applications.
Geolocation API is one example that provides the user’s location to their web applications.
What is REST API?
Rest API is also known as Restful web Services. Rest API is used to get a talk from the client-side to a server for getting data using the HTTP and HTTPs request in a server-client architecture. Rest APIs are a convention for those HTTP services which provide support to create, read, update and delete data. Using Rest API, users send a request(consist of URL), and in response, the client gets data.
Why use Restful APIs?
Consider a web app which shown your employee’s data. And this data is not static. You have to change this data from time to time, which is store in a webserver. So to access data, the request is sent by using Restful APIs, and in response, you get a JSON and XML having a hierarchical structure.
Some examples of the Rest APIs are:
- Twitter REST API.
- Facebook REST API.
- Google Translate REST API
