I'm setting up a delayed chained payment in PHP
I'm setting the feesPayer to SECONDARYONLY
$payRequest->feesPayer = 'SECONDARYONLY';
the transaction is made to the primary receiver
but the second leg of the chained payment (from primary to secondary receiver) is still pending.
then 90 days passed (payKey expired) and I did not complete the payment.
who pays the fees when the payKey expires?
