I beg to differ.

When something happens on PayPal then can hit a location on your site
to inform you of this. Usually the url would be something like:

  http://myapp.com/ipn

Your app then needs to confirm the request back to PayPal to check
that it is legit.

This makes me think that a controller is needed - perhaps I am wrong?

All too well :)
