To enable tracking of bookings that come from your own website, cross-site tracking must be activated in your Google Analytics account. This is explained here: [GA4] Set up cross-domain measurement - Analytics Help (google.com). The snippet from the Google Analytics account must then be stored in the "Tracking Code" function.
You can use the following URL patterns to measure key points in the booking process:
- Website visit: Page URL contains: .belbo.com
- Successful booking: Page URL contains: .belbo.com/finalConfirmation/success
