I discovered that I could check the IPN message sent by PayPal by visiting Profile > Preferences > Instant Payment Notification preferences > IPN History page and then clicking the appropriate Message ID link.

On the Subscriptions and Recurring Payments Variables page, it's shown that the custom variable is sent for the txn_type
of subscr_cancel
. Since there's no way to send a new custom variable, does that mean PayPal is sending the same custom variable sent during subscr_signup
?
