Google add to cart conversion value not send to GAD

Google Tag Manager Server Container
1

Hi Stape team and community,

I’m tracking Add to Cart conversions via Magento 2 + Stape server container. The event fires correctly, items and prices appear in the dataLayer, but the conversion value is always counted as 1 instead of the actual product value.

What’s working / checked:

  • The dataLayer contains items[] with price, quantity, and total value.
  • The add_to_cart event is received in the Stape server container.
  • Default Stape + Magento 2 setup is used.

Where I need help:

  • Do I need to explicitly map value / currency in the Google Ads Conversion tag (server-side)?
  • Which variable should I use — {{event.value}}, {{ga4_event.value}}, or something else?
  • Does Stape expect the GA4 payload to include ecommerce.value, or does it calculate it automatically from items[].price * items[].quantity?
  • Is there any Magento 2-specific setting that controls whether the conversion value is sent?

I can share screenshots or exports (server tag, client event, and debugger) if needed.

Thanks a lot for your help!

Hey @Mirac_Samutoglu the issue is related to the fact we’re not currently pushing top-level value in view_item and ATC events. Therefore 2 points:

  1. We will be addressing this in upcoming plugin update and then it will all work seamlessly

  2. For now you can manually map value into the tag.
