Bug: Duplicate Checkout Events & Incorrect Purchase Event Trigger yireo / Yireo_GoogleTagManager2LokiCheckout

[sertacyilmaz-3webapps]

Description

We are seeing duplicate event triggers during the checkout process.

• The begin_checkout and add_payment_info events are each triggered three times when the user is logged in.
• When the user is not logged in, these events are triggered twice.

Additionally:

• The purchase event is being triggered even when the payment is cancelled.

Expected Behavior

• begin_checkout and add_payment_info should only be triggered once per checkout session.
• The purchase event should only be triggered after a successful and completed payment.

Actual Behavior

• Duplicate begin_checkout and add_payment_info events.

• purchase event fires even when the payment is cancelled.

I've tested this myself. For both a guest and a logged-in customer, in my own environment, the events begin_checkout, add_payment_info, add_shipping_info and purchase take place 1 single time.

The Yireo GoogleTagManager purposefully has a mechanism built-in that prevents (!) duplicate events from happening. Note that the add_payment_info event is triggered multiple times if you change the payment method. Not doing that would result in wrong statistics. If you don't want to see user interaction, do not rely upon client-side tracking.

How do you conclude that duplicate events take place?

How do you conclude that these events are indeed triggered by the Yireo GoogleTagManager2? I trust that you have enabled debugging in the module to allow very simple debugging in the error console. Please add screenshots of your proof that the Yireo GoogleTagManager2 is causing these events.

Also note that the Yireo GoogleTagManager2 LokiCheckout integration does not trigger the purchase event. This event is triggered on the success-page. If the success-page is hit, in the event of a failed payment, either there is a delayed canceling of the order and you switch to server-side tracking. Or the settings of the Yireo GoogleTagManager have not been configured correctly.

Here you have screenshots from the console and gtm dashboard(7,9). You can see the begin_checkout event firing multiple times. I have the latest versions of the gtm modules.

Then, unfortunately, I'm unable to duplicate this and I don't where to offer free voluntary support from here.
