This snippet automatically redeems a WooCommerce coupon code via a direct URL. I generate a QR code from this URL, and I have set up a QR code scanner on my website. When the QR code is scanned, it automatically redirects to the URL, and the coupon code is redeemed, awarding points to the user. I use the MyCred plugin for points.

However, I want to modify this setup so that instead of including the entire URL in the QR code, I generate QR codes that only contain the coupon code. Then, the QR code scanner should read only the coupon code and redeem it automatically without needing to include a URL.

rihgt now i’m using this type url for coupon redeeming function
