I'm trying to perform a mass deletion of existing remediation tickets in my subscription. The previous administrator had created a policy that opened a ticket for every severity 4 & 5 vulnerability in the subscription and didn't do anything with them. Fast forward a year, there are now well over 140k tickets in there that just need to be deleted. I've already deleted all of the policies but can't delete all the tickets at once. The only method I've been able to do so far is delete 500 tickets at once (500 because that's the most I can view on a single page).
Is there an API call for this?
