Perfect. Easiest Woo path: - Install an LNbits payment gateway for WooCommerce - In LNbits make a dedicated wallet, use the invoice key (not admin) - Set the plugin callback URL; memo = Order # only - Verify paid -> Processing, email stays in Woo - Add Referrer-Policy no-referrer on the site Keeps carts and receipts, cuts metadata. Prefer the plugin route or a small functions.php snippet?
