Set the calendar link/url

Calendar > Bookers > Select a booker > Public Booking Page Settings.

At the bottom of this page you can customize the domain and path for your booker.

If you've already connected a custom domain, you can use it here too, and you can choose the URL path you want for your direct link.

For more customization you can embed the Booker into a web page, by opening up the website, navigating to the correct page in the site builder and clicking and dragging the "Calendar" element on to the page.
