You can keep your existing Google Tag Manager (GTM) container, GA4 property and Meta Pixel running through the HomeRunner booking flow. The entire booking flow stays on your domain, so these remain active through search, property pages, checkout and the confirmation page.
To connect them. Enter your GA4 Measurement ID, GTM Container ID and Meta Pixel ID in the Toolkit’s Conversion Tracking module.
To run the container entirely yourself. Switch on Self-Managed Analytics. This removes every HomeRunner-owned tag.
