We are using the ASI.IBO.dll version 1.0.3072.24284 for a custom checkout solution. Paypal has confirmed that both the first and last name provided are being entered into the first name field on their end. The CreditDebitCardHoldersName property of the ASI.IBO.Financials.CPayment object apprently puts the value into the First name field on the Paypal side and leaves the Last name field empty. We intermittently receive a response code from Paypal when testing of 10513. The 10513 error code indicates that the last name of the credit card holder is empty and therefore invalid. Has anyone else encountered this?
