HTTP Response Codes

When using advanced features, you may encounter these specific HTTP response codes:

Status Code	Description	When It Occurs
`410 Gone`	Visit limit reached	QR code has exceeded its maximum visit count
`402 Payment Required`	Plan limit exceeded	Your plan doesn't support this feature or has reached its limit
`403 Forbidden`	Password required	QR code is password protected but no password was provided
`401 Unauthorized`	Incorrect password	Wrong password was provided for a protected QR code

Best Practices

Security Considerations

Strong Passwords - Use strong, unique passwords for protected QR codes
Regular Updates - Change passwords periodically for sensitive content
Access Monitoring - Monitor access attempts and failed authentications
Fallback URLs - Provide meaningful fallback URLs for expired QR codes

Performance Optimization

Reasonable Limits - Set visit limits that make sense for your use case
Caching - Implement appropriate caching for frequently accessed QR codes
Error Handling - Handle all possible HTTP response codes in your applications
User Experience - Provide clear messaging when limits are reached
