API Error Handling Tutorial 🛠️

Error handling is a critical aspect of building robust APIs. Properly managing errors ensures a better user experience and simplifies debugging. Here's a guide to common practices:

1. Error Types to Handle ⚠️

• HTTP Status Codes: Use standard codes like 400 (Bad Request), 404 (Not Found), 500 (Internal Server Error)
• Custom Error Objects: Return structured responses with error, message, and code fields
• Validation Errors: Handle input validation failures gracefully

2. Best Practices ✅

• Always return meaningful error messages
• Use consistent status codes for similar issues
• Log errors for debugging (see Logging_Tutorial)
• Implement rate limiting for abuse prevention

3. Example Response 📜

{
  "error": "Invalid input",
  "message": "The request contains invalid parameters",
  "code": 400
}
