You will have to delete them all manually. No such feature added yet!

Thank you! But it's sad that a software like Qualtrics does not have that feature. There should be at least a warning .

I'm in a similar boat, but with *only* 5159 tickets. It's wild that there are no admin tools to mass edit/delete tickets. I saw this post from two years ago, but it's already been archived with no action:
https://community.qualtrics.com/XMcommunity/discussion/6651/enhanced-ticketing-managementI'm currently looking into whether we can make an API call to delete them automatically:
{"embed-error": true}https://api.qualtrics.com/74478ffd002fc-delete-a-ticket

upvoting this! I too have tickets that were created off incomplete responses when I closed a survey. I’m dealing with “small” numbers of 2.5k, but that’s still so much manual work!

There is no such UI functionality to delete all tickets at one go, but if you are familiar with Qualtrics API then you can follow the below steps:

• Export the ticket details (in CSV), it has the column ticket number which is the ticket key id.

• Here is the Qualtrics API - https://api.qualtrics.com/74478ffd002fc-delete-a-ticket
• Run this API through postman application, refer this youtube video for executing the API based on values from the CSV
