REST API Meaning

What does REST API mean?

If you’ve ever considered collecting data from another source on the internet, such as Twitter, you’ve probably come across the term “REST API.” But what exactly is a REST API? What does it have to offer you? What are your plans for it?
API stands for an application programming interface. It explains how to construct a server program that connects to any client program.
API integration connects two or more programs via their APIs to share data and execute a joint function. As a result, the applications can interact with one another.
Let’s move on to REST APIs now that we’ve defined API.
This post will teach you all you need to know about REST APIs to understand the API documentation and use them successfully.

What is REST API?

An API is a collection of rules that let programs communicate. The developer creates the server API and lets the client use it.
REST specifies the API design. “Representational State Transfer” Create an API that follows a set of rules. One of these principles is that when you link to a URL, you should obtain a resource.
Each URL is a request, and the data returned is a response.
Consumers to communicate with cloud services such as Amazon, Google, and Twitter using REST-based APIs.
For example, let’s say you want to find superman films on YouTube. Superman videos appear when you open YouTube and key in “superman” in the search box. A REST API is comparable. You ask for something, and the service responds with a list of results.

How Does It Work?

REST determines the API’s structure. Developers must follow a set of rules while creating an API. Generally speaking, a link to a URL must return some data.
Whenever a URL is typed into a browser, it is referred to as a Request.
When using REST APIs, a transaction is broken down into a series of discrete components. Aspects of the transaction are dealt with by each component. A flexible development strategy is made possible by the modularity of the method.
A REST API makes use of HTTP methods as defined by the RFC protocol. It makes use of the subsequent requests:

GET is used to retrieve data.
PUT modifies the current data state, such as an entity or file.
POST is used to create data.
DELETE options for eliminating it.

Why Use RESTful APIs?

Consider the following example to better understand REST API concepts and structure.
Suppose you want to practice “data integration” on YouTube. You type ‘data integration’ into the search bar, and a list of data integration videos appears. Right?
Also, RESTful APIs function in a You ask for something, and the service returns a list of results.
REST means that all calls are stateless. This means the REST API can’t maintain data between executions, which is beneficial for cloud apps. In case of failure, stateless constituents can be readily reallocated. They can also be resized to account for load changes. Because any constituent instance can send any request.
REST is the preferred protocol for internet communication because no data is stored that must be retrieved later. As previously stated, REST API technology may connect to cloud apps by just altering the URL.
REST application programming interface can be used in the same manner to transfer files from one cloud to another.

3 REST API Terminology

Client

When a server’s API is used by a client, it is referred to as the client. For example, whenever you visit the LinkedIn site, your browser accesses the API and uses the received data to display information.

Resource

Users, hashtags, and media types like photos can all be resources in an API. An identifier for each resource (name or number).
REST’s core information abstraction is the resource. A resource identifier is used in REST APIs to identify the resource being transmitted between two or more entities.

Server

A server is any system that a client wishes to use. The API interface is used to reply to requests from clients. Not complete access, but just a representation of the source.
This is similar to the way a smartphone app displays YouTube videos on its own User interface. REST API is used to view YouTube video content without hosting it on your server.

The Benefits of Using REST API

These REST API features make data and application integration more efficient.

Scalability
Independence
Portability
