Pay-Pal IPN (Instant Payment Notification)

Verify all Pay-Pal transactions (from Buy Now Buttons) to ensure orders are completed before allowing the download of your products. Keeps track of the number of product downloads and limits the number of attempts a buyer can download product. If products are updated, administration can reset download attempts for free upgrades and send an email to each customer of that product notifing them of that update. Create, edit, delete and search transactions within administration. Download script can be made to match your website and will only allow download links to work from listed sites.
