These values are absent for non-USD payments so that IPN scripts will not process these
amounts as USD. However, legacy IPN scripts will continue to work as before as long as the
merchant only receives USD payments.
For more information about IPN multi-currency variables, see “Currency and Currency
Exchange” on page 152.
Dispute Notification
Buyers can register claims about payments; such claims are called cases. PayPal notifies
merchants about new cases with email and with IPN.
There are two kinds of cases:
z Complaint: A buyer has used the PayPal Resolution Center to register a claim about a
payment to a merchant.
NOTE: After notification about a complaint claim, merchants must log in to PayPal to use
the Resolution Center to respond to the case.
z Chargeback: A buyer has filed a complaint with a credit card company that has resulted in
a chargeback. The credit card company notifies PayPal about the reason for the
chargeback. After investigating the case, PayPal notifies the merchant of any action
required.
IPN variables for cases include the type of case, the reason, and other information about the
case. For details about all variables and their possible values, see “Dispute Notification
Variables” on page 56.
