Handling Errors
It is possible for some merchant payments to succeed while others fail. Parallel payments
creates multiple independent payments, and each payment is subject to its own validation and
review.
If part of a payment fails, the ACK value is PartialSuccess. To find the error, check the
value returned in PAYMENTINFO_
n_ERRORCODE in the response to
DoExpressCheckoutPayment.
NOTE: If an error is generated by any of the payments in the call to SetExpressCheckout,
the transaction fails.
