Shopware extension troubleshooting

Power-ups aren’t working

Issue: You have enabled Custom Loader or Cookie Keeper in the Shopware extension settings, but the features aren’t functioning correctly.

Solution: Simply enabling Custom Loader or Cookie Keeper within the extension settings isn’t sufficient on its own. To ensure these features function correctly, please first enable the corresponding power-up within your Stape account, and then activate it in the extension settings.

Cookie Keeper and Custom Loader work only when the server container is hosted on Stape. Cookie Keeper also needs a paid Stape plan.

Webhook tests don’t show in GTM Preview

Issue: The Send test webhook feature triggers a request directly from Shopware, rather than a site visitor's browser, which is why it typically won't appear in the Server GTM (sGTM) Preview.

Solution: To view these test webhooks in the sGTM Preview, follow these steps:

1. Open Preview in your sGTM container.
2. Enable the sGTM Preview header config power-up in your Stape account and follow the setup instructions.
3. Click Send test webhook in the extension.
4. You should now see the request appear in the sGTM Preview.

Item IDs don’t match Merchant Center (or another catalog)

Issue: You’re noticing that tracking data fails to match across platforms like Google Ads or Merchant Center, despite the Stape extension being configured.

Solution: The extension generates the items array directly from your Shopware product catalog. If your external platforms (such as Google Ads or Merchant Center) use different product identifiers, the tracking data can’t be synchronized. To resolve this, you can use the following method:

Create a Custom JavaScript Variable in Web GTM or a variable / transformation in sGTM to construct your required catalog format (for example, prefixing shopware_ or using item_sku instead of item_id in your Google Ads / GA4 tags).
