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,
DoExpressCheckoutPayment response
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.
