Test in Preview mode before you publish

Importing changes nothing on your live site until you press Submit. Use that gap.

Click Preview in GTM, place a real test order (a 100% discount code works), then refund it.
Check each tag fired once, on the right event, with value, currency and transaction ID filled in.
Decline cookies and check _ga, _fbp and _gcl_au are not set.
Watch GA4 DebugView, Meta Test events and Google Ads diagnostics, then publish with version notes.

How to import

In GTM open your container, then Admin.
Choose Import container and select the downloaded file.
Pick a workspace (a new one called "Ecomtoolpack import" keeps it tidy).
Choose Merge, never Overwrite on a container that already has tags.
Choose Rename conflicting tags, triggers and variables, so nothing you have is replaced.
Read the preview of what will be added, then Confirm.
Remove any old GA4, Ads or Meta tags that now do the same job, so nothing fires twice.

Shopify custom pixel

Paste this into Settings, Customer events, Add custom pixel. It loads your container inside Shopify's pixel sandbox and pushes the same data layer events from analytics.subscribe, including on checkout and the thank-you page. Field names follow Shopify's Web Pixels API; check them against Shopify's current reference before going live.

What's in the file

Google tag and GA4 events

One Google tag for your G- ID, then a GA4 event tag per event reading value, currency, transaction ID and items from the data layer.

Google Ads purchase

A conversion tag on purchase with value, currency and order ID (so Google can drop duplicates), plus the Conversion Linker.

Meta Pixel with dedup IDs

The base pixel and ViewContent, AddToCart, InitiateCheckout and Purchase, each with an eventID. Send the same ID from the Conversions API and Meta counts it once.

Consent first

Consent Mode v2 defaults on Consent Initialisation, before any tag. Meta tags need ad_storage granted. Google tags use their built-in consent checks.

Tidy names and folders

Tags named Platform - Type - Detail, Custom Event triggers CE - event, variables DLV, Const and JS, grouped in folders.

Your data layer does the work

The container listens for GA4-shaped events. Shopify's custom pixel, GTM4WP on WooCommerce or your developer pushes them.

Want the whole tracking plan, not just the container?

The Tracking & Attribution skill in Ecomtoolpack plans your events from the order backwards, sets consent for each market, deduplicates Meta CAPI, sets up enhanced conversions and gives you a test checklist. Paste this container in and ask Claude to check it.
