Verifying tracking

🛠 Dev

A quick checklist to confirm events are flowing from the store into GTM.

In the browser

1. Open the live store and the browser dev tools console.
2. Trigger an action (open the vehicle lookup, select a postcode, advance an installation step).
3. Inspect window.dataLayer — you should see a push whose event matches the normalized name (e.g. cbp_drawer_open, cbp_postcode_select). See the data layer contract for expected shapes.

In GTM Preview

1. Use GTM Preview/Debug (Tag Assistant) connected to the store.
2. Because tracking runs inside Shopify's Web Pixel sandbox, confirm events appear as Custom Events in the Preview timeline.
3. Check that your Custom Event triggers match the normalized event value (not source_event_name). The catch-all regex is ^cbp_.+.

Common gotchas

• No events at all — confirm the pixel is installed under Settings → Customer events with the current web-pixel.js contents, and that the GTM container ID is GTM-T7Z4P3GQ.
• Standard events but no cbp_* events — the theme's analytics.js publishes those; check the feature is actually present on the page and not erroring in the console.
• Events in dataLayer but tags not firing — your GTM trigger name probably doesn't match the normalized event value.
