Finalizing integration
Next, after your buttons you need to add this code:


All set. Now you are ready to start tracking sales from your Google Checkout account.
Note: There is one more option named "Process whole cart as one transaction" in Google Checkout plugin setup. If you check this option, pap will register whole cart as one big transaction. In this case do not forget to use merchant-private-data instead of merchant-private-item-data to transmit custom value information to PAP4.

Every Google Checkout user should contact Google checkout team at checkout-api-support@google.com and request to whitelist their domain. Otherwise the tracking will not work.
