Best Practices for RESTful API Design
November 26, 2025
Designing a good API is crucial for the success of your application. Here are the best practices I've learned over the years.
Use Proper HTTP Methods
- GET: Retrieve resources
- POST: Create new resources
- PUT/PATCH: Update existing resources
- DELETE: Remove resources
Consistent Naming Conventions
Use plural nouns for resource names and keep URLs lowercase with hyphens for multi-word names.
Proper Status Codes
Always return appropriate HTTP status codes:
- 200 - Success
- 201 - Created
- 400 - Bad Request
- 401 - Unauthorized
- 404 - Not Found
- 500 - Server Error
Versioning
Always version your APIs to allow for backward compatibility as your API evolves.
