RESTful API Development

REST API Concepts

RESTful APIs are the foundation of communication between modern applications.

REST Principles

• Stateless: Each request contains all necessary information
• Cacheable: Responses can be cached
• Uniform Interface: Consistent interface
• Client-Server: Separation of concerns

Endpoint example

GET /api/users/123
{
  "id": 123,
  "name": "John Doe",
  "email": "john@example.com"
}
