API Design Best Practices

REST API Design

• Use nouns for resources (/users, /orders)
• Use HTTP methods correctly (GET, POST, PUT, DELETE)
• Use proper status codes
• Version your API (/v1/users)
• Use plural nouns

HTTP Status Codes

• 200 OK - Success
• 201 Created - Resource created
• 204 No Content - Deletion success
• 400 Bad Request - Client error
• 401 Unauthorized - Authentication required
• 403 Forbidden - Not allowed
• 404 Not Found - Resource not found
• 500 Internal Server Error - Server error
