RESTful API

Published on: Sept. 29, 2024

Overview

RESTful API (Representational State Transfer API) is a way to build web services that allow different systems to communicate over the internet using standard HTTP methods.

Key Features

• Resources: Data entities (like users, posts) are treated as resources.
• HTTP Methods: Uses standard HTTP methods to operate on resources:
  • GET: Retrieve data
  • POST: Create new data
  • PUT: Update existing data
  • DELETE: Remove data

Example API Endpoints

• GET /posts: Retrieve a list of blog posts.
• POST /posts: Create a new blog post.
• PUT /posts/1: Update the blog post with ID 1.
• DELETE /posts/1: Delete the blog post with ID 1.

Why Use RESTful API?

• Simple and standardized: Easy to use and integrate.
• Stateless: Each request from the client to the server must contain all the information needed to understand and process the request.

How It’s Used

• Frontend apps (like websites or mobile apps) communicate with the backend (servers) using RESTful APIs to perform operations like fetching data or submitting forms.
