The YCBM Booking reference is a unique identifier given to bookings. It's formatted like XXXX-XXXX-XXXX
To find the booking reference for a meeting, head to the calendar event.
By default, all calendar events contain the booking reference but it's possible to remove this when configuring booking page settings.
For account owners looking for a booking reference, it can be found on the bookings dashboard: https://app.youcanbook.me/#/bookings by clicking Details on the booking.
