Google Checkout

SSL Certificates supported

Only certain SSL certificates are supported by Google Checkout when it does a callback to the server to update your database. While it is not essential to have a compatible SSL certificate, it does mean that your orders will be reported as "Canceled" because no "cardtype" is recorded for the order. You will need to manually process the orders using Google's administration if you do not have a support SSL certificate installed. The current list of certificates supported are:

Google Checkout does not callback in Live mode

As a requirement for Google Checkout, you need to have the callback script accessible via HTTPS. However, it may not callback successfully due to a 401.1 error:

Unauthorized: Access is denied due to invalid credentials.

Please refer to your web hosting company of the following page for how to fix this issue:
