I sell tickets myself.
Here’s how I pull it off.
Use the orders API to create Line items and name each line item as a ticket then if the number of tickets are small enough you can add the ticket names in the note field of the payments API so when the order is paid you can search for the names of the tickets in the dashboard. I think the note parameter allows for over 500 characters so you’ll get enough space for ticket names if there are only a few per order.
