Hi @Areed15,

Thanks for sharing this question with us.

First, I’d double-check that you have the Klaviyo onsite javascript installed on your site. It wouldn’t be installed by default for the Shift4Shop integration. If you’re interested, you can find the list of ecommerce integrations that automatically install this code here.

Next, I assume you were using the Viewed Product code outlined in this section of our “How to Integrate with Shift4Shop” documentation? If not, make sure you also followed the steps there to install the Viewed Product code snippet.

If both of the above steps were done correctly, your code should look something like the screenshot at the bottom of that same article (screenshot here for reference):

Also, keep in mind that in order to capture a Viewed Product event generally, the user would have to be cookied on their browser prior to viewing the item. This means that the user previously did one or both of the following: a) filled out a Klaviyo sign-up form or b) clicked on a Klaviyo email. You can find more information on that here. And you can test your web tracking by following this section of that same article.

I hope that’s helpful :)
