Thanks so much for reaching out!
I’m not quite sure what you are referring to. Are you looking to show the coupon code slot on a ticket? If so, are you referring to the ticket that is emailed to the attendee?
Either way, our Themer’s Guide is a great place to start, as it can guide you to which templates can be copied and edited to help you achieve the results that you are looking for:

Once I have a bit more information, I can provide you with some more specific advice.
Let me know!
Thanks,
Jaime
