Analytics with Google Tag Manager

Reval publishes GA4-standard e-commerce events into your Google Tag Manager container’s dataLayer. You decide, from your own GTM panel, which destinations they go to (GA4, Meta Pixel, TikTok, Google Ads) — without touching anything in Reval and without asking anyone for changes.

Connecting your container

Copy your Container ID from GTM → Admin (format GTM-XXXXXXX).
In Reval: Settings → Analytics — Google Tag Manager, paste the ID and save.
Done: the checkout and the thank-you page load your container automatically. To turn it off, clear the field and save.

The tags you configure in your container run inside your store’s checkout. You are responsible for what your GTM account loads there: use a strong password and 2FA on Google, and grant container access only to people you trust.

Available events

`begin_checkout`

Published when the checkout loads, with the purchase the customer is about to make:

{
  event: "begin_checkout",
  ecommerce: {
    currency: "ARS",            // your store's currency
    value: 12500.0,             // recurring total of the chosen plan
    items: [
      { item_id: "gid://shopify/ProductVariant/…", item_name: "Product A", price: 12500.0, quantity: 1 }
    ]
  }
}

`purchase`

Published on the thank-you page once the subscription was created and the charge approved. It’s emitted exactly once per purchase: reloading the thank-you page doesn’t duplicate it.

{
  event: "purchase",
  ecommerce: {
    transaction_id: "…",        // stable id of the subscription
    value: 13500.0,             // total charged (products + shipping)
    tax: 1000.0,                // reported tax portion, 0 when not applicable
    shipping: 0.0,
    currency: "ARS",
    items: [                    // includes one-time add-ons, if there were any
      { item_id: "gid://shopify/ProductVariant/…", item_name: "Product A", price: 12500.0, quantity: 1 }
    ]
  }
}

Before each event, { ecommerce: null } is published, following GA4’s convention for clearing the previous object.

Verifying it

In GTM, open Preview (Tag Assistant) and navigate to your store’s checkout: you should see the container loaded and begin_checkout on the timeline.
Complete a test purchase: purchase appears on the thank-you page with the transaction detail.
Reload the thank-you page: purchase does not appear again.

What to do with the events

In your container, create one tag per destination using these events as triggers. The names and structure follow GA4’s e-commerce schema, so the GA4 tag understands them with no manual mapping, and for Meta/TikTok/Ads you map value, currency and items to the destination’s fields from dataLayer variables.
