If you would like to track how many bookings or enquiries you are receiving from a particular booking form, you can add the following to the widget script and in Collins, track how many bookings you're getting from this specific form.
<script> DMN.addCustomData('source', 'XXXXX'); </script>
The X's will be replaced with the custom source you want to display (for example, Christmas) within your Collins admin. Any bookings/enquiries made on this form will have the custom source in the 'Additional Details' section and will be tagged with this source in your Enquiries page download.
This is especially useful for Christmas pages or any major advert campaigns with the booking form included.
