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.

To specify a notification URL For a/an :

1. PayPal Payments Standard button:

   notify_url HTML form variable

2. NVP API operation:
   NOTIFYURL field of the DoDirectPayment , DoExpressCheckoutPayment , or DoReferenceTransaction request.

3. SOAP API operation:

   NotifyURL field of the DoDirectPayment , DoExpressCheckoutPayment , or DoReferenceTransaction request.

4. Adaptive Payments API operation:
   ipnNotificationUrl field of the Pay or Preapproval request
