I was able to use BOI to create a payment with the default customer credit card on it by calling the functions DefaultCustomerCreditCard() on the payment object and also setting on the payment object the property ProcessInBatch = "YES".  If I do not set ProcessInBatch and let BOI process the payment when calling nWrite function, then I get an error that says "The credit card transaction request to Sage Exchange cannot be processed."  Is is possible using BOI to tell the order to use the DefaultCustomerCreditCard and automatically pre-auth the card?
