🚧

This issue is caused by the New Shopify Checkout Structure.

Overview

Are you using Google Tag Manager on your Shopify thank you page and seeing a drop in conversions beginning at the end of August/early September 2022?

Chances are your checkout has been upgraded to Shopify's new checkout.

If you are on an Elevar data layer version 2.34 or below then you will need to upgrade to our latest version to ensure you don't miss any conversions.

Are You On The New Shopify Checkout?

• Navigate to the checkout pages or place an order, you should see the new checkout URL "checkouts/c/"
• If you are still on our version 2.34 and below dataLayer, this causes GTM not to fire the "dl_purchase" event. Hence, all purchase tags (e.g., GAds Conversion, TikTok, Facebook, etc.,) that are using the purchase trigger will not send the data.

How To Verify Data Layer Version

Shopify Source

If you are on our Shopify source, then you are on a data layer version of 3.9 or higher. No further checks needs for the data layer version.

• Begin on the Elevar homepage and use the left-hand menu to click on the "My Tracking" tab. If the Shopify Source says "Detected on Live Theme" and there are no other messages, then you are on a data layer version of 3.9 or higher.

Theme Files:

If you haven't upgraded to the Shopify Source you can find your data layer version in your Shopify theme files .

• Locate and click on the three dots next to your current theme. An additional drop-down menu will appear, click on the "Edit Code" tab.
