When designing a RESTful API, follow these essential guidelines to ensure clarity, reliability, and scalability:

1. Use RESTful Principles

  • Resource-oriented endpoints (e.g., /users instead of /get_users)
  • Standard HTTP methods: GET, POST, PUT, DELETE for CRUD operations
  • Stateless interactions to maintain scalability
REST_API

2. Version Control

  • Include version numbers in URLs (e.g., /v1/users)
  • Avoid breaking changes by maintaining backward compatibility

3. Status Codes

  • Use 200 OK for success, 400 Bad Request for client errors, 500 Internal Server Error for server issues
  • Always return meaningful error messages in JSON format
STATUS_CODES

4. Documentation

  • Provide Swagger/OpenAPI documentation for endpoint details
  • Include examples for request/response formats

5. Security

  • Implement OAuth 2.0 or JWT for authentication
  • Use HTTPS for all communications
SECURITY_PRINCIPLES

6. Consistency

  • Keep naming conventions uniform (e.g., snake_case or camelCase)
  • Standardize response structures across endpoints
