Stay On Top of New Meeting Additions

When someone adds a meeting to your calendar, you need to know right away. Notis sends a Slack reminder with the event details, so you never discover a surprise meeting 5 minutes before it starts.

Trigger

Event Created

Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info.

Action

Create a reminder

Creates a slack reminder with specified text and time; time accepts unix timestamps, seconds from now, or natural language (e.g., 'in 15 minutes', 'every thursday at 2pm').

Why this helps

Executive dysfunction can make it hard to regularly check calendar notifications. New event additions get overlooked, leading to surprise meetings or calendar anxiety. Having a dedicated Slack notification creates a single source of truth.

  • Know about new meetings before they're 10 minutes away
  • Reduce calendar anxiety by consolidating notifications to Slack
  • Quickly scan new event details instead of opening your calendar
  • Catch scheduling conflicts early

Setup

Build it in a few focused steps.

  • 1Connect your Google Calendar and Slack workspace to Notis.
  • 2In the portal Automations tab, create a new automation named 'New Event Alert'.
  • 3Enter this prompt: 'Every time a new event is added to my calendar, send me a Slack reminder with the title, time, attendees, and any meeting link.'
  • 4Select 'Event Created' as your trigger.
  • 5Choose a Slack channel for these notifications.
  • 6Test by having someone add an event to your calendar and verify the Slack alert.

Questions about this workflow

Will this trigger for events I create myself?

Yes, which helps you confirm what you just scheduled.

Can I filter out low-priority events?

Tell Notis: 'Only alert me for meetings with 3+ people' or 'Skip personal time blocks.'

What if someone sends a calendar invite via email instead?

Once you accept it, Google Calendar will show it as created, and Notis will notify you.
