Thank you text
This text will be shown as a new ticket confirmation when you create a ticket from the website. You can edit this either as HTML or TEXT as per your needs. In this text mode, you can also use custom HTML code. Macros are available to replace the ticket data.
Thank you page URL (optional)
You can set up a custom thank you page from the WordPress pages. But you can not use macros in this. If you insert the page URL in this setting, the customer will be redirected to it after creating a ticket. Leave empty to use the above thank you text.
