Express Checkout API Errors
10417 Transaction
cannot
complete.
The transaction cannot complete
successfully. Instruct the
customer to use an alternative
payment method.
It is possible that the payment method the customer
chooses on PayPal might not succeed when you
send
DoExpressCheckoutPayment. The
most likely cause is that the customer’s credit card
failed bank authorization. Another possible, though
rare, cause is that the final
OrderTotal is
significantly higher than the original estimated
OrderTotal you sent with
SetExpressCheckout at Integration Point 1,
and the final
OrderTotal does not pass PayPal’s
risk model analysis.
If the customer has no other PayPal funding source
that is likely to succeed,
DoExpressCheckoutPaymentResponse
returns error code 10417.
Instruct the customer that PayPal is unable to
process the payment and redisplay alternative
payment methods with which the customer can pay.
