API Design Patterns

Design consistent, developer-friendly REST APIs with resource naming, HTTP semantics, and versioning.

When to Activate

• Designing new API endpoints
• Reviewing existing API contracts
• Adding pagination, filtering, or authentication
• Planning API versioning strategy
• Building public or partner-facing APIs

Quick Start

1. Use nouns (plural, kebab-case) for resource URLs, not verbs
2. Apply correct HTTP method (GET/POST/PUT/PATCH/DELETE)
3. Return appropriate status codes (200/201/400/401/403/404/429)
4. Use consistent response format (data + metadata + error structure)
5. Implement pagination (cursor-based preferred) and filtering
6. Require authentication and check authorization per resource

Key Concepts

• Resource naming — Plural nouns in kebab-case; use verbs sparingly for actions
• HTTP semantics — Each method has idempotency/safety properties; honor them
• Status codes — Signal intent precisely (400 for validation, 422 for semantic error)
• Error format — Consistent structure with codes, messages, and field details
• Versioning — URL path versioning (v1, v2); non-breaking changes don't need new version

Common Usage

Most frequent patterns: - CRUD endpoints (GET, POST, PUT, PATCH, DELETE) - List endpoints with pagination and filtering - Sub-resources for relationships (users/:id/orders) - Authentication headers and permission checks - Rate limiting headers and strategies
