IPN Refund

[johnlanglois]

When my client issues a refund via PayPal their system sends a notice to the notify_URL file that normally processes everything.(Website Payment Standard)

Which variable would let me know the incoming notice is a refund?
I need to use that to send out a different email notice.

Thanks.
