Hi folks. Does anyone have any experience using this Shopify integration with GA4? https://docs.growthbook.io/integrations/shopify I have it working up to a point (features and metrics) but can't get experiments working. As far as I can see the 'experiment_viewed' event is not sent, as it is in other GB implementations. This part of the docs suggests it should work automatically, but do I need to add tracking myself?

When a user views an experiment, the code above will fire an event that tracks which variation the user saw. If you have Google Analytics 4 (GA4) or Segment installed on your store, you don't have to do any additional configuration. If, however, you need to use a different analytics provider, you can follow our guide here.

Hi Tom 👋 We have lots of folks using Shopify with GA4 and BigQuery. I assume you are using the pre-built <script> tag, right?

Hi @brief-honey-45610 thanks for taking a look. There is a public URL, though it is just a dev store: https://cambraydesignlimited.myshopify.com/ Using the GA4 Debugger for Chrome I can see the standard GA4 events being sent and also if you click where it says "Image banner" a custom event is sent, which is intended to be the metric. Unlike other implementations I can't see the "experiment_viewed" event being sent though, although this is visible in the data layer.

Hi Tom, I haven't forgotten about you. We are catching up on support requests from the holiday weekend in the US.

Thank you! I meant to message but I did actually come up with a solution - sending the experiment_viewed event explicitly via a custom event tracking function worked fine. The issue before seemed to be that the event was added to the data layer but did not sent to GA4, and this may be a GTM configuration issue. I'm curious about it but I don't think there is any issue on the GB end.

Hi Tom, thanks for the update. I"m glad to hear you got it sorted! It can be tricky getting GTM, GA4, GrowthBook and BigQuery all working together.
