TOPIC: is address info above donation sent to payment gateway?

If it is then you can get a lower rate by including the credit card address. IS that address above the donation info sent to the gateway? What CB fields does it pull from?

Yes the address is sent to authorize.net. It pulls from whatever was typed into the DT Donate form. Doesn't pull from CB... unless CB has already populated the form with address info.

so we need to specify that the address needs to be the address on file for the credit card - that should probably be put on there by default somewhere.

Yes, as with any online transaction, your address given should be the billing address. You could make additional notes for that above the form.
