PaymentPal

PaymentPal lets you accept PayPal transactions through your website automatically. Through PayPal's unique Instant Payment Notification (IPN) system, the included "post-back" script will be accessed by PayPal to let you know the status of a transaction. This enables you to take PayPal payments to the next level by automatically activating member accounts, delivering electronic products, etc. without having to manually log into PayPal to accept payments. All you do is add the code you want to be executed according to the transaction status and it will be automated.
