Stop Wasting Time on Cancelled Meetings with Instant Alerts
Last-minute cancellations leave you checking your calendar at the last minute. Get a Telegram alert the moment an event is cancelled so you can reclaim that time immediately.
Trigger
Event Canceled or Deleted
Triggers when a Google Calendar event is cancelled or deleted. Returns minimal data: event_id, summary (if available), and cancellation timestamp.
Action
Send Message
Send a text message to a telegram chat using the bot api.
Why this helps
An organizer cancels a meeting 10 minutes before it starts, but you don't see the cancellation. You waste 15 minutes getting ready, finding the meeting link, or waiting in a room until you realize it's been deleted.
- Reclaim your time instantly when a meeting is cancelled
- Stop wasting energy preparing for meetings that don't exist
- Reduce the stress of showing up unprepared to a non-existent meeting
- Catch organizer edits and cancellations in real time
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and Telegram to Notis.
- 2Create an automation: "Alert me on Telegram immediately when any calendar event is cancelled or deleted."
- 3Select the trigger: "Event Canceled or Deleted" from Google Calendar.
- 4Choose Telegram as your notification destination.
- 5Verify it works by testing with a calendar event you'll delete shortly.
Questions about this workflow
Does this include events deleted from your own calendar or just cancellations from organizers?
It catches both. If you delete an event or an organizer cancels it, you get a Telegram notification.
What if I accidentally delete an event? Can I undo it?
The Telegram message gives you enough info to recreate it. Google Calendar also has a trash bin for recent deletions.
Can I silence alerts for low-priority events?
Yes. Tell Notis to alert only for meetings with 3 or more attendees, or specific organizers. You control what matters.
