Identifying Your IPN Listener to PayPal
Dynamically Setting the Notification URL
Dynamically Setting the Notification URL
You can specify an IPN listener for a specific payment; this is the only way to receive IPNs
associated with Adaptive Payments. In this case, PayPal sends the IPN message to the listener
specified in the notification URL for a specific button or API operation instead of the listener
specified in your Profile.

you can choose whether or not to resend them.
