Hi,
Google Checkout will automatically request new information
if the
credit card authorization failed. There's currently no XML
request
you can send that will ask the customer to input new
purchasing
information. In regards with the AVS and CVN, AVS is used
for address
verification CVN is used for credit card verification. AVS
has
several possibilities such as full match, zip match, address
match, no
match, and unsupported. As for CVN the possible values are
match, no
match, unavailable, and error. Typically fraudulent
transactions are
caught by Google Checkout systems, however for any orders
that get
past, it's up to the merchant's discretion to look at the
AVS and CVN
information. To cancel an order if it hasn't been charged,
you can
use the cancel-order XML request or cancel it in the
Merchant center.
More information about the cancel order request can be found
at:

ut/developer/index.html#cancel_order_example
Please remember that Google Checkout does provide a Payment
Guarantee
policy for all orders that are eligible.
