CF_PayPal_IPN is a coldfusion PayPal tag that is a plug and play piece of code which will enable you to track commercial transactions on your web site.  Using PayPal's API you can easily take advantage of PayPal's Instant Payment Notification.  When a user purchases something on your web site through PayPal, your database will be updated noting that the transaction was completed.  When this occurs your user can receive a personalized message from you regarding time frame for delivery, what steps are needed next, or just a thank you for doing business with us

The plus version of this code includes the pages needed to make maintaining the add on possible without changing any of the coldfusion code. This is the same base code that is in the CF_PayPal Pro.
