We have no Google Adwords integration. Can probably be done with CB Auto Actions though acting on CBSubs triggers. The Google Analytics plugin uses the onCPayAfterPaymentStatusUpdateEvent trigger. It has the following variables.
Code:
/**
* Handles changes of payment basket $paymentBasket payment statuses events
* This function may be called more than one time for events different than the Completed or Processed state if there are multiple notifications
*
* $unifiedStatus status mappings with e.g. Paypal status:
* CB Unified status Paypal status
* Completed <-- Completed
* Processed <-- Processed, Canceled_Reversal
* Denied <-- Denied, Expired, Failed, Voided
* Refunded <-- Reversed, Refunded, Partially-Refunded
* Pending <-- Pending, In-Progress
* RegistrationCancelled <-- A new cb registration got cancelled by user (e.g. paypal cancel payment button)
*
* @param UserTable $user User paying
* @param cbpaidPaymentBasket $paymentBasket CBPaid Payment basket being paid (corresponding to PayPal variable names)
* @param cbpaidUsersubscriptionRecord[] $subscriptions CBPay Subscriptions being paid
* @param string $unifiedStatus new unified status: see above
* @param string $previousUnifiedStatus previous unified status: see above
* @param string $eventType type of event (paypal type): 'web_accept', 'subscr_payment', 'subscr_signup', 'subscr_modify', 'subscr_eot', 'subscr_cancel', 'subscr_failed'
* @param cbpaidPaymentNotification $notification notification object of the payment
* @return void
