How to sell a hidden ticket for an event
For each ticket type, you can set who can see it. If you set a ticket type to "Hidden," it will not be visible or available to anyone.
Selling with a secret URL
Hidden ticket types have a secret URL. This secret URL allows website visitors to still select the hidden ticket type. This allows you to share the ticket type with a very select group.
When selling hidden ticket types, the availability of the ticket type and the capacity of the event are of course taken into account.
