You can display a post-purchase message on both the confirmation page and confirmation email to your ticket buyers to thank them, remind them to follow you on social media, share links, send parking or dress code details, or simply ask them to share your event with family and friends.
First click the Details tab on your Event Dashboard.
Near the bottom of the page you will find Post Purchase Message. Click edit and enter your message and then click Save Changes.
If you want to add a hyperlink, follow the format shown in the example ( [[ http://www.website.com | Link Label ]] ) and you're good to go!
