insert Booking parameters when redirecting to a URL on confirmation page

hi, according to this article when redirecting the confirmation page to my URL  (show your own confirmation page) - I should be able to pass as parameters the details that were collected through the booking process. this is from the documentation:

List of supported Booking parameters

These parameters can pass booking details along with your custom URL.

Booking details

          1.  booking_id=<value>
          2.  workspace_uuid =<value>
          3.  workspace_name =<value>
          4.  assigned_to =<value>  (staff or resource name)
          5.  service_uuid =<value>
          6.  service_name =<value>
          7.  booking_start_time =<value>  (represented in ISO 8061 format in customer timezone)
          8.  booking_end_time =<value>   (represented in ISO 8061 format in customer timezone)
          9.  booking_cost =<value>
          10.  booking_cost_paid =<value>
          11.  booking_currency =<value>

 
but how exactly the syntax work? since we passing the values collected on the booking, so the <value> above should be what a user entered. How it's passed in the URL?
thanks!
