To set up complimentary tickets, you simply set up a ticket as usual and set the price to 0.00.
If you want to set up free tickets as part of a promotion you can also add on a promo code (which can easily be shared out) or a one-time link.
If you only wish specific people to access the ticket, a one-time link is the best option as it generates a link that can only be used once (you may want to restrict the amount of tickets that can be purchased in one order).
If you are running a promotion on social media, or as part of a press release and are happy for the links to be shared out, a promo code is a really easy way to do this.
