psigate and :invoice

[Jodi Showers]

Psigate's recurring billing api builds the charge quantity by summing
up invoice itemInfos, It also builds autobuilds invoices for query

<ItemInfo>
<ProductID>NEWSPAPER</ProductID>
<Description>TORONTO STAR</Description>
<Quantity>1</Quantity>
<Price>25</Price>
<Tax1>2</Tax1>
<Tax2>1.25</Tax2>
</ItemInfo>

<ItemInfo>
<ProductID>Three Month Promotion</ProductID>
<Description>Flyer Coupon</Description>
<Quantity>1</Quantity>
<Price>-10</price>
</ItemInfo>

In order to support the common AM interface, where only an :amount is
provided, I would then need to generate a single generic
ItemInfo...hiding capabilities of the gateway

...else if :invoice could hold a sub hash of itemInfo line items -
paypal seems to be the sole user of the :invoice - used for a callback
it seems

else a new hash ? :line_items ?

thoughts?

thanks.

See the CyberSource gateway for :line_items format. You can keep the
same interface accepting an amount, but the gateway wouldn't use the
information.
