Overview

Design REST APIs that are intuitive, consistent, and follow industry best practices for resource-oriented architecture.

When to Use

• Designing new RESTful APIs
• Creating endpoint structures
• Defining request/response formats
• Implementing API versioning
• Documenting API specifications
• Refactoring existing APIs

Quick Start

Minimal working example:

✅ Good Resource Names (Nouns, Plural)
GET    /api/users
GET    /api/users/123
GET    /api/users/123/orders
POST   /api/products
DELETE /api/products/456

❌ Bad Resource Names (Verbs, Inconsistent)
GET    /api/getUsers
POST   /api/createProduct
GET    /api/user/123  (inconsistent singular/plural)

Best Practices

✅ DO

• Use nouns for resources, not verbs
• Use plural names for collections
• Be consistent with naming conventions
• Return appropriate HTTP status codes
• Include pagination for collections
• Provide filtering and sorting options
• Version your API
• Document thoroughly with OpenAPI
• Use HTTPS
• Implement rate limiting
• Provide clear error messages
• Use ISO 8601 for dates

❌ DON'T

• Use verbs in endpoint names
• Return 200 for errors
• Expose internal IDs unnecessarily
• Over-nest resources (max 2 levels)
• Use inconsistent naming
• Forget authentication
• Return sensitive data
• Break backward compatibility without versioning
