Google Checkout module for ZC 1.3.x (beta)

[inkspot]

[FONT=Times New Roman]Being a novice to Zen-cart myself, after carefully following all the steps, I finally got Google Checkout to work, at least as far as paying for merchandise. However, it still failed to show "Level 2 integration." That is, it failed to adjust product inventory, add the customer, and only showed my Google Checkout default shipping prices.[/FONT]

[FONT=Times New Roman]It turned out that my domain host did not have a SSL certificate installed for my website (or I should say I did not buy one when I set it up). My domain host offers a shared SSL certificate for my domain (through which I can link to googleresponsehandler.php), but the certificate works only with html pages, not php pages like Zen-cart. Also I have a budget domain package with a dynamic IP. So I would also have to convert to a dedicated IP to have SSL certificate with my domain host. The total cost of the changes is over $100.[/FONT]

[FONT=Times New Roman]Now the funny thing is the PayPal IPN doesn't require an SSL certificate and works just fine on my site.[/FONT]

[FONT=Times New Roman]Take home message for novices: If Google Checkout basically works, but does not change your store's admin database, you probably are missing a SSL certificate for your site (so check before you begin).[/FONT]
