Welcome to the API Design tutorial! This guide will walk you through the fundamentals of creating effective and user-friendly APIs. Whether you're a beginner or an experienced developer, these principles will help you build robust interfaces.

Core Principles 🛠️

  1. Consistency

    • Use uniform resource naming (e.g., /users vs /user_list).
    • Maintain predictable request/response formats.

  3. Security

    • Implement authentication (e.g., OAuth 2.0, API keys).
    • Use HTTPS for all communications.

Best Practices ✅

  • Versioning: Always include version numbers in your API routes (e.g., /api/v1/users).
  • Error Handling: Return meaningful error messages in JSON (e.g., {"error": "Invalid input"}).
  • Documentation: Provide clear endpoints and parameters in your API docs.
