Orders API - Override IPN URL

[Andelous]

Hey, I've been using the Orders API in conjuction with the Java SDK, and I was wondering if there's any way to override the default Notification URL for Instant Payment Notifications. I followed the tutorial in this link, and adapted it to run server-side.

I've been searching through the forums and the documentation with no luck so far. Thanks for your attention, any help is appreciated.
