Is it possible to pass UTM parameters?

YouCanBook.me can handle UTM parameters. 

However, in order for UTMs to be tracked in Google Analytics, you must pass them through after the booking to a page with Google Analytics code embedded.

To do this, use the Redirect to a specific URL after a booking. feature.

(Redirecting to a page after the booking is required as YouCanBook.me pages to not support Google Analytics tracking code).
