How to configure a webhook for downtimes that are to going to be expired

hey there,

we already have a slack integration for warings, critical etc.

how can i archive to get a notification for downtimes that are to going to be expired ?!

Thx

You could either use Livestatus or the Web API and then fire the webhook to notify you.This has to be scripted nd can be scheduled as a cron as site user.
