Each certificate is automatically generated by HikaSerial and includes a unique serial number, an expiration date, and a QR code. We would like our clinic administrator to scan the QR code, open the HikaSerial redemption page with the serial number automatically passed to it, and confirm redemption without manually entering the code. Only authorized administrators (Super Users) should be allowed to redeem certificates. What is working * Gift certificates are generated correctly using the AttachSerial plugin. * Unique serial numbers and expiration dates are generated correctly. * QR codes are generated successfully. * Manual redemption through the HikaSerial frontend form works perfectly. * After manual redemption, the serial status changes from Assigned to Used. * The Group Filter Consumer plugin is configured for Super Users only. The problem When we generate a QR code containing a redemption URL with HikaSerial parameters, Joomla converts the URL into an incorrect SEF format. For example, we tried: However, the QR code contains a URL similar to: The serial number is lost and replaced with . We also tried URL-encoding the square brackets ( and ), but the result was the same. Using a simple parameter such as preserves the serial number in the SEF URL, but does not successfully pass it to the redemption handler. When opening the generated link, HikaSerial displays a confirmation page. However, after submitting, it returns to the "Enter your serial code" form instead of redeeming the certificate. We also temporarily disabled Joomla SEF routing for testing. The HikaSerial confirmation page opened, but we have not established whether the serial number was correctly processed in that configuration. SEF has now been re-enabled. Our questions * What is the correct URL format for QR-code-based certificate redemption in HikaSerial 6.1.1 with Joomla 6? * How can we prevent the parameter from being converted into ? * Is there a recommended way to generate a redemption URL directly through AttachSerial while keeping Joomla SEF enabled? * Can we configure QR-code redemption so that only Super Users can confirm and consume certificates? * Is there a built-in solution that does not require modifying HikaSerial or Joomla PHP files? We would appreciate a working URL example or recommended configuration for this setup. Thank you for your assistance.
