A Quick Guide on Rest API

Hello, Flocks👋, This guide will help you to get a basic idea of working with the Rest API.

What is Rest API?

Whether you are a front-end developer or back-end developer, you need to know about the Rest API(s).

Representational State Transfer (REST) API(s) is a way to make communication between the front-end and the back-end of the application.

Rest API(s) communicate through HTTP requests to perform CURD (Create, Read, Update, Delete) operations in a resource.

The Rest API(s) allows you to create, read, update, and delete data from the database or resource using the backend server.

How It Works?

When a client request is made via a RESTful API, it transfers a representation of the state of the resource to the requester or endpoint.

This information, or representation, is delivered in one of the several formats via HTTP: JSON(Javascript Object Notation), HTML, XLT, Python, PHP, or Plain text. JSON is the most generally popular file format to use because, despite its name, it’s language-agnostic, as well as readable by both humans and machines.

Data Format Supported

• application/JSON
• application/xml
• application/x-wbe+xml
• application/x-www-form-urlencoded
• application/form-data

Example:

If you make a visit to the following link:

https://api.github.com/users/akashkothari98

You will get a JSON Response:

{
  "login": "akashkothari98",
  "id": 38093413,
  "node_id": "MDQ6VXNlcjM4MDkzNDEz",

  "received_events_url": "https://api.github.com/users/akashkothari98/received_events",
  "type": "User",
  "site_admin": false,
  "name": "Aakash Kothari",
  "company": null,

  "location": "Rajkot,Gujarat",
  "email": null,

  "created_at": "2018-04-05T04:41:49Z",
  "updated_at": "2022-11-05T05:09:25Z"
}

Here’s what happened:

1. you typed the URL.
2. The front end makes a request.
3. The Backend parses the request based on the data received from the front end.
4. The Backend returns the JSON data.
