Set up Google Tag Manager tracking for online bookings

This guide shows how to install Google Tag Manager on your Caspen booking flow.

Overview

Google Tag Manager helps you track online bookings so you can see which campaigns and channels are driving results.

Caspen lets you add your GTM container to your online booking experience, so your tracking can run as part of the booking process and send conversion data to tools like GA4, Google Ads, and Meta.

If your booking form is embedded on your website, your usual website tracking may not capture everything reliably. Adding GTM in Caspen helps ensure your tracking is recorded correctly.

Important note

To use Google Tag Manager with Caspen Online Bookings, you must contact Caspen Support. We will guide you through the activation process to enable it for your account.

3. Save (top-right).

Step 4: Create your tracking tag and attach the trigger

You can either create one tag per platform, or combine multiple tracking scripts in one Custom HTML tag (simple for a first setup). In this guide, we will use one Custom HTML tag so the setup stays simple.

1. In Google Tag Manager, go to Tags → click New.

1. Enter a Tag name of your choice (top-left).

2. In Tag configuration select the tag type: Custom HTML.

3. Paste the tracking code you want to run. You can add more than one script if needed.

1. In Triggering, select the trigger: CaspenBookingCompleted

2. Click Save.

Tip

If you are not sure what code to paste for a specific platform, contact that provider (for example Google or Meta) and ask what you should add to the Custom HTML tag for tracking.

Step 5: Publish your GTM changes

1. In Google Tag Manager, click Submit.

1. Add a version name, for example Caspen bookings tracking.

2. Click Publish. Once your changes are published, your tags are live and can start tracking bookings through Caspen.

Frequently asked questions

How do I pass extra IDs or attribution details with the custom event?

This is configured in Google Tag Manager. If you need to pass additional IDs or attribution details through your tags, refer to Google Tag Manager guidance or contact Google Support for help setting up the right variables and tag configuration for your platform.

Do I need to set up Google Tag Manager on my website as well?

Setting up Google Tag Manager on your website is a separate task because your website code is managed outside Caspen. You would only set it up on your website if you also want to track website activity, such as which pages people view before they start a booking.

This guide does not cover installing Google Tag Manager on your website. If you need help with website setup, contact Google Tag Manager support or your website provider.
