I'm having trouble distinguishing between the different currency values returned by the SOAP API's GetCart method. Does anyone know the distinct purposes of the following properties:
Beyond their specific purposes, how are the above values affected by:
Here's what I've figured out so far:
Order_total, order_value, and amt_to_charge seem to always be the same. I can't tell when or why they'd ever be different.
Amt_paid_now increases when I apply a gift certificate payment.
Balance_to_charge decreases when I apply a gift certificate payment.
HandlingCharges is the total of all fees.
SubTotal is the order_total / order_value / amt_to_charge minus HandlingCharges.
