Full Form of API

The full form of API is “Application Programming Interface”. An application programming interface is a way for two or more computer programs to communicate together. It is a type of software interface, that offers a service to other pieces of software. A document or standard that describes how to build or use such an interface is called an API specification.

What is API?

APIs are mechanisms that enable two software components to communicate with each other using a set of definitions and protocols. For example, the weather software system contains daily weather data. The weather app on your phone “talks” to this system via APIs and shows you daily weather updates on your smartphone.

How do APIs work?

The full form of API is explained in the above section. API architecture is usually explained in terms of client and server. The application sending the request is called the client, and the application sending the response is called the server. So in the weather example, the weather database is the server, and the mobile app is the client end.
There are 4 different ways that APIs can work depending on when and why they were created.


These APIs use the Simple Object Access Protocol (SOAP). Client and server exchange messages using XML. This is a less flexible API that was more popular in the early days of automation.


These APIs are called Remote Procedure Calls (RPC). The client completes a function (or procedure) on the server, and the server sends the output back to the client end.

Websocket APIs

Websocket API is another modern web API development method that uses JSON objects to pass data. A Websocket API supports two-way communication between client apps and the server end. The server can send call-back messages to connected clients, making it more efficient than REST API.


These are the most popular and flexible APIs found on the web these days. The client sends requests to the server as data. The server uses this client input to start internal functions and returns output data to the client. Let’s look at REST APIs in more detail below also the full form of API has been explained above.

What are REST APIs?

REST stands for Representational State Transfer. REST defines a set of functions like GET, PUT, and DELETE that clients can use to access the server data. Clients and servers exchange data using the HTTP protocol.
The main feature of REST API is statelessness. Statelessness means that servers do not save client data between requests. Client requests to the server are similar to URLs you type in your browser to visit a website. The response from the server is plain data, without the typical graphical rendering of a web page.
What are the benefits of REST APIs?
We have described the full form of API and the methods by which the API works. REST APIs offer four main benefits:

1. Integration 

Integration is the most important feature of API.  APIs are used to integrate new applications with existing software systems. This increases development speed because each functionality doesn’t have to be written from scratch. You can use APIs to leverage existing code.

2. Innovation 

Entire industries can change with the arrival of a new app. It permits the user to create new features. Businesses need to respond quickly and support the rapid deployment of innovative services. They can do this by making changes at the API level without having to re-write the whole code.

3. Expansion

APIs present a unique opportunity for businesses to meet their clients’ needs across different platforms. For example, maps API allows map information integration via websites, android, iOS, etc. Any business can give similar access to their internal databases by using free or paid APIs.

4. Ease of maintenance

The API acts as a gateway between two systems. Each system is obliged to make internal changes so that the API is not impacted. This way, any future code changes by one party do not impact the other party.
