<span style=”font-size: inherit;”>Hi,</span>

Thank you for checking this and for sharing the video — that really helped.

I revisited the issue on my side and was able to identify the cause. It looks like the problem was related to the modal checkout script. I made a small change in the modalCheckout.js file, and after that adjustment, the flow is now working correctly for me as well.

The fix is a single line added in modalCheckout.js — add .off() before .on() to prevent duplicate handler attachment:

File: btcpay-greenfield-for-woocommerce/assets/js/frontend/modalCheckout.js (line 191)

if (selected_gateway.startsWith(‘btcpaygf_’)) {
// Remove any existing handler first to prevent duplicates.
checkout_form.off(‘checkout_place_order’, submitOrder);
// Bind our custom event handler to the checkout button.
checkout_form.on(‘checkout_place_order’, submitOrder);
}

Now, when applying points:

• The order is created with the correct discounted price

• The BTCPay invoice also reflects the discounted amount properly

• Both modal overlay and redirect checkout are functioning as expected

So it seems the issue was likely due to a script conflict or how the modal was handling the updated totals during checkout.

At this point, everything is working fine on my end. I’ll continue to monitor it, but it looks resolved after this fix.

Really appreciate your support on this!

Best regards,
