Navigate to your site, and then trigger the events that you want to test.
In the extension, click the on the Google Tag Manager tag. The Data Layer section should display the payload of the event that was triggered.
Any other tags that are loaded by Google Tag Manager are also listed in the extension. You can click these tags to review the data that was sent to them.
I’ve flagged this to the Help Docs team - but in future, for feedback on the merchants docs I’d recommend reaching out to support directly to flag content issues.
I couldn’t help but laugh (and grimace) at this ‘update.’ It’s as if Shopify is saying, ‘Here’s a glimpse of our event—enjoy watching it, but if you’re relying on GTM, good luck!’ It feels like a half-measure that leaves us high and dry rather than offering any alternative solution.
Hi Zamartz, the Shopify pixel helper will tell you which events were subscribed to properly by your GTM custom pixel and let you know about runtime errors.
To understand what GTM is doing after receiving the event from Shopify, there are a couple options. You can use the tag assistant to tell you which Google tag are loaded by GTM, there are chrome extensions for the specific pixel you are tracking (Facebook, TikTok, etc) or you can look at specifc network calls in the dev console. In the update, the link to the Shopify pixel helper pages has more detailed instructions on different ways to test your custom pixel.
