There are many situations where it might be useful to set some rules about what your customers can buy. For example, you might want to ensure child tickets can only be booked with an adult ticket for your family event, or offer a free carer's ticket with an accessible booking.
To set up ticket dependencies
Head to your event and choose 'edit event and tickets'.
Create all of the ticket types you're selling for your event.
First, create the ticket type someone must purchase. In this example, I'll create a "Day ticket" for a wellness festival, which people must purchase before they can book any of the sessions running during the festival.
For the ticket that you want to be dependent on another ticket, open the 'Advanced settings'.
Select the checkbox called 'Only available with other ticket types'.
Then, select the ticket(s) that must be purchased alongside this one.
Add an error message your customer will see in the box called 'Invalid selection error message'. For example, I've written: "Please purchase an entry ticket to join sessions".
Save your tickets and repeat for as many dependent ticket types you need.
You can use ticket groups to add headers to your checkout to explain which tickets must be purchased.
If a ticket buyer tries to buy a dependent ticket type without an essential ticket, they'll see your error message.
💡 Things to note
If all of your essential tickets are sold out, but there are still some dependent tickets available, your event or occurrence will show as 'Sold out'.
