Infralution IPN.NET provides a complete ASP.NET solution for automating your purchasing and product licensing system using PayPal's Instant Payment Notification (IPN) mechanism.

IPN.NET can be used in conjunction with the Infralution Licensing System for a complete licensing and purchasing solution or you can integrate your own licensing system into IPN.NET. We supply full source code for the IPN.NET Server so that you can customize it to your own needs.

IPN.NET includes a sophisticated IPN Test Tool that allows you to fully test and debug your IPN Server on your local development machine. This tool alone is worth the purchase price.
