Once you have created tickets, you can create promotional codes.
In your Back-Office > Ticketing > Promotion codes > click on "Add a promotion code" button.
- Choose your code (you can generate a random code if necessary)
- Select the eligible ticket(s) and/or add-on(s).
- Specify the percentage of the discount.
Note that you can fix a maximum number of uses for each code.
You have also the possibility to disable them.
