If you want to redirect customers to a booking page with predefined values for Service, Category, Employee, or Location, you'll need to add the appropriate URL parameter for each value to the link.
To create the link, use the ID of the required values, which can be found either in the database or by using the 'Developer Tools' in a web browser.
Here's an example of a link with URL parameters:
www.example.com/?cat_id=1&service_id=2&staff_id=3&loc_id=4
