Hi,
I create a PayPal express checkout in Rapido. The checkout works perfect when there is no shipping cost but, if the total price includes a shipping cost I get this error:
An error has happend 10413. Transaction refused because of an invalid argument. See additional error messages for details.. The totals of the cart item amounts do not match order amounts.
The error is fired only with PayPal. With VISA and Invoice there is no error.
Does anybody know how to fix it?
Regards,
Tomas
