Each live event type has its own booking page. Open the live page and copy its public URL from the address bar. Share this link when you want someone to book that specific appointment. For a paid event type, share the normal public page, not the Test paid booking link.
Your public booking overview lists live event types set to Listed. Share the overview if you want customers to choose between them. A Hidden event type is left off the overview but remains bookable by anyone with its direct link; hidden does not mean private or password-protected.
Only share a page after you have checked its duration, availability, location, questions, payment settings and customer emails. For a paid booking, send the event type link rather than the regular checkout product link so the selected time is held while the customer pays.
