Once you've set up online bookings and the bookings link is in 'published' status; we recommend you to try and make a dummy booking by clicking on your 'bookings link'. This way you'll be able to test out whether you've set up your booking platform correctly. 

Load the online booking page and make a dummy (test) booking to review and test the workflow you created. Once you have submitted a booking, the system will generate an email confirming the booking and you can see the new booking in your online booking dashboard; If this is the case, then you're good to go.
