MediaWiki Extension

MW:Extension:PayPal is an extension for creating PayPal donation forms using a <paypal> tag. PokerCoder requested adding IPN support to the extension through this RentACoder job and has accepted User:Nad's bid to complete the work.

IPN

Instant Payment Notification, included with Website Payment products, Express Checkout, and Standard Checkout, is available to PayPal Premier and Business members. Instant Payment Notification allows you to integrate your PayPal payments with your website's back-end operations, so that you get immediate notification and authentication of any PayPal payments and disputes you may receive.
