Google Analytics Tag Manager GTM with One Page Checkout OPC - compatibility

Google Analytics Enhanced Ecommerce (WeltPixel GTM) is compatible with the default Magento 2 Checkout.

Custom/One Page Checkout (OPC) Compatibility

If a custom checkout (OPC or other) uses Magento 2’s standard API calls, tracking data should be pushed correctly.
If the custom checkout alters how API calls are handled or changes the checkout flow, the extension may require compatibility adjustments.
In most cases, only the checkout step events are affected; other events, including the Success Page (purchase), typically continue to work.

Because implementations vary, each custom checkout must be tested in your environment to confirm full coverage.

If you’re using a popular OPC solution and would like native compatibility, please add a request in our community forum thread:

We periodically review the most-used requests and consider them for future releases.
