Accepting 50 additional SSL root CAs

Posted by Jacob Moon, Google Checkout Team

If you want to implement the Notification API or if you want to perform Merchant Calculations for tax and shipping, Google Checkout requires a valid SSL certificate installed on your server. Until now, we've been accepting SSL certificates issued by a limited number of SSL Certificate Authorities (CA). However, we've added 50 additional root CAs to our list, so you can easily find a suitable SSL certificate for your callback handler. Here's a list of all SSL root CAs accepted by Google Checkout.

On a related note, if you're having trouble receiving notifications or performing merchant calculations even though you have a valid SSL certificate, take a look at this troubleshooting guide.
