REST API: Complete Guide to Design, Development, and Integration

A REST API (Representational State Transfer Application Programming Interface) enables communication between different software systems over the internet using standard HTTP methods. It allows applications to send and receive data efficiently, making it a core technology behind modern web and mobile applications.

What is a REST API?

A REST API is an architectural style that uses HTTP requests to perform operations such as retrieving, creating, updating, and deleting resources. Each resource is identified by a unique URL and typically exchanges data in JSON format.

A REST API (Representational State Transfer Application Programming Interface) is a set of rules that allows different applications to communicate with each other over the internet using HTTP protocols.
A REST API works through client-server communication. The client sends an HTTP request to a server, and the server responds with the requested data or confirmation of an action performed.

REST APIs commonly use the following HTTP methods:

  • GET – Retrieve data
  • POST – Create new resources
  • PUT – Update existing resources
  • PATCH – Partially update resources
  • DELETE – Remove resources
REST APIs allow seamless integration between systems, enabling web apps, mobile apps, and services to communicate efficiently and scale easily.
