Google Wallet - SSL / https handled completely by Google?

Question

For Google Wallet, I'm wondering if a SSL certificate for https needs to be setup on the serverside, or if all https access is done on Google's servers?

In the wallet tutorial, I notice that all https addresses are from google -

Answer 1

An SSL certificate is not required on the server side. The postback call from Google mirrors back the original transaction data plus an order Id. If you are using the sellerData field, depending on your particular situation, you may consider encrypting that information.
