Customer Problem

The customers would like to directly delete a massive amount of alerts on a search query, such as alerts that are created older than 12 months, directly on the UI.

Possible Solutions

N/A

Workarounds

Create a Saved Search on the UI, and script to fire List Alert API call with the Saved Search first, and multiple DELETE API calls to purge them out.

Note: There is no support for this kind of search yet: Alerts that are created older than 12 months.
