Is the data in the Billing Address pane required for use with Authorize.net? In my case, we are not using any shipping modules in Ubercart, since it is delivered locally, so the client would like to have only the Delivery Address pane displayed since only one address is necessary. However, we are using Authorize.net as our payment gateway, so I'm guessing they will need an address to compare with the billing address for the credit card.

In looking at uc_authorizenet.module, I can see that the billing address is sent as will as the delivery data (so maybe I answered my own question). Just out of curiosity, though, why does Authorize.net care where the delivery address is?

Thanks.
