Best Practices for Error Handling

1. Always Check Response Status
   • Verify HTTP status code before processing response
   • Handle both success and error cases
2. Implement Retry Logic
   • Retry failed requests with exponential backoff
   • Only retry idempotent operations
   • Respect rate limits
3. Log Error Details
   • Store error responses for debugging
   • Include transaction IDs in logs
   • Monitor error patterns
4. User-Friendly Messages
   • Display appropriate error messages to end-users
   • Translate technical errors into user-friendly language
   • Provide clear next steps when possible
5. Security Considerations
   • Never expose sensitive information in error messages
   • Validate all input data
   • Handle timeouts gracefully
