Installing the Rezgo Base GTM Listener

Rezgo automatically broadcasts standard ecommerce events as they happen. To capture these, you will need to import our GTM Listener Recipe. This recipe contains a script that “listens” for messages from the Rezgo iframe and translates them into standard GTM events.

Prerequisites

Before importing the recipe, ensure you have:

• Google Tag Manager installed on your website in the parent frame (more info).
• Publishing rights in Google Tag Manager

Importing the Rezgo Base Listener

To simplify your setup, we provide a pre-configured GTM container file. 

1. Download the tracking recipe here: Rezgo Base Listener
2. In GTM, navigate to Admin > Import Container.
3. Choose the downloaded file and select your Existing workspace.
4. Important: Choose Merge as the import option and select Rename conflicting tags to ensure you don’t overwrite your existing setup.
5. Click Confirm.

Configuration steps

After importing, you only need to perform one manual step:

1. Enter Preview Mode in GTM and perform a test booking on your booking website. You should see the ecommerce events appearing in the summary column.
2. Once verified, hit publish in GTM.

Data payload & schema

Every event includes a “Payload”, a collection of data about the tour, price, and currency.

Key Data Points Captured:

• Items Array: Details including item_id, item_name, price, and quantity.
• Monetary Value: Total value and currency (e.g., CAD, USD).
• Marketing Data: coupon codes and discount amounts for promotional tracking.
• Customer Data (Purchase Only): Hashed user_data (email, phone, address) is included in the purchase event to support Enhanced Conversions in Google Ads and Meta.

Example: The Purchase Event

When a booking is completed, Rezgo pushes a rich data object into your Data Layer:

// Example of a successful purchase payload

{
  event: "purchase",
  rezgoEvents: true,
  ecommerce: {
    transaction_id: "5Y1H4K9D6C9Q4Q5I",
