Comp tickets online

We are looking into allowing comp tickets online, my question is about the CheckoutEx3 method. Do we just pass 0 (zeros) for the iCCType, iCCMonth, ICCYear variables? My concern was the note in the documentation for iCCType "Pass 0 to omit a payment method if saving an unpaid order" Since the tickets are comps and comps are always considered paid, is this the route we go or do we pass some sort of cash payment method to the call?

 

Thanks,

Marty
