ClickCartPro and EuropaCart have Google Checkout functionality built-in.
The Google Checkout integration used by this software is highly advanced and uses callbacks from Google to calculate taxes, discounts and shipping in order to accurately calculate order totals. With this integration, the only checkout functionality that is present in the base software checkout, that is disabled during Google Checkout are the custom sale and custom surcharge functions. This integration supports realtime calculations between the software and Google using all shipping methods (Realtime, Product-Based, Custom, Zone-Based, Not Shipped) available, all tax systems (Standard and EU VAT) available, and fully supports discount codes.
Below is a step-by-step guide on how to set up Google Checkout in the software.
1 Install ClickCartPro 7 or EuropaCart 7. Be sure to indicate a valid SSL (https) URL for your secure URL during the installation. Google Checkout requires an SSL URL for callbacks.
2 Get a Google Checkout account at http:checkout.google.com/. After your account is set up, login to it. Under the My Account section, take a look in the My Products section. There you will see an option for Checkout. Access that option. This brings you to Google’s Checkout Admin Panel.
3 At the top of the Google’s Checkout Admin Panel there are tabs at the top. Select the Settings tab.
4 Within the Settings tab, access the Tax Setup section. As the software calculates taxes using callbacks, it is best not to have any information loaded in the tax setup table. If there are entires there from a previous shopping cart software installation, we recommend deleting those entries.
5 Within the Settings tab, access the Shipping Setup section. As the software calculates shipping charges using callbacks, it is best not to have any information loaded in the shipping methods table. If there are entries there from a previous shopping cart software installation, we recommend deleting those entries.
6 Within the Settings tab, access the Integration section. There, copy your Google Merchant ID and Google Merchant Key. You will need them later.
– Check the box next to ‘My company will only post digitally signed carts.’.
– Enter the SSL (https) URL that points to the /utilities/googleco.php file in your ClickCartPro 7 or EuropaCart 7 installation. Access that file with a browser to make sure you enter a valid SSL (https) URL. If you get a message stating ‘The request received by the Google Checkout webservice was empty.’ when you access that URL, you’ve got the right one. The URL will look something like:
https://www.yourdomain.com/store/utilities/googleco.php
– For the ‘Callback contents’ section, choose the ‘Notification as XML’ selection.
– For the ‘API Version’ section, choose ‘Version 2.5’ and leave the box under ‘Notification Filtering’ unchecked when it appears.
