Learn REST API design best practices including naming conventions, HTTP methods, and status codes.
REST API Design: Best Practices
Designing well-structured REST APIs is crucial for building maintainable applications.
Design Principles
- Use Nouns, Not Verbs - /users instead of /getUser
- Use HTTP Methods Correctly - GET, POST, PUT, DELETE
- Use Plural Nouns - /users instead of /user
- Version Your API - /api/v1/users
- Use Consistent Naming - Follow conventions across endpoints
Status Codes
Use appropriate HTTP status codes: 200 for success, 201 for created, 400 for bad requests, 404 for not found, 500 for server errors.
Documentation
Always provide comprehensive API documentation using tools like Swagger or Postman.
