The variables available to that trigger are as follows.
Code:
$_PLUGINS->trigger( 'onCPayAfterPaymentStatusChange', array( &$user, &$paymentBasket, &$subscriptions, $unifiedStatus, $previousUnifiedStatus, $occurrences, $autorecurring_type, $autorenew_type ) );
For stripe the payment type attached to basket is usually just always "stripe". You are not likely to be able to differentiate the payments reliably. You can try though using the following substitution on the above trigger.
[var2_payment_type]
