payment reference tracking

Instant payment notification (IPN) is a method for online retailers to automatically track purchases and other server-to-server communication in real time. This allows E-commerce systems the opportunity to store payment transactions, order information and other sales internally. IPN messages can represent payment success or failures, order transaction status changes, accounting ledger information and many others depending on the payment gateway.
The payments industry is an evolving market, technology like IPN and instant payment are now used in the retail market and in the domestic sphere, but they are expected to evolve into the corporate, business-to-business (B2B) segment and cross-border space.
