The other method is [[../IPN|Instant Payment Notification]] (IPN).<br /> <br /> PDT is accomplished via data passed back to the merchant&#039;s web site by the customer&#039;s browser after completing the transaction. This obviously poses the risk that the customer may cancel out before this happens, leaving the merchant&#039;s site unaware that the transaction has taken place. [[../IPN|IPN]] prevents this problem by directly notifying the merchant&#039;s web site of the transaction as soon as it occurs (i.e. PayPal&#039;s server contacts the merchant&#039;s server without involving the customer).</div>
