Hi Eugene -
I am sorry for my vagueness, I should have been clearer! I signed up for an Google checkout account and was trying to set it up to match with my cart. The notes in the Google API say this:
Also you have to go to 'Settings, Integration' and set in field 'API callback URL' your URL to google_checkout.php
For example:
http://www.your_site.com/payments/google_checkout.php
and set 'Callback method' to 'XML'.
When I do that in my google account, it states that the http MUST be a https://
So I guess my question is... is this step necessary to make the Google API function properly? Or does this step do something that is not required? If it is necessary, then I have answered my own question that yes you need an SSL.
Thank you for your help..... is there a help page for the google checkout API? I have the notes that show up in the admin area, but I admit that I was still slightly confused!
