Record confirmed Calendly no-shows from Slack

After a missed meeting, the admin follow-up is easy to postpone. Notis can record a confirmed no-show on the relevant Calendly event.

Trigger

Channel Message Received

Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Action

Create an invitee no-show

Marks an invitee, identified by their existing and valid uri, as a 'no show' for a scheduled event.

Why this helps

Unrecorded no-shows can make later follow-up or attendance review harder to manage.

  • Capture attendance follow-up while the event is fresh.
  • Keep a consistent record of confirmed missed meetings.
  • Reduce post-meeting admin steps.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Calendly to Notis once through the portal.
  • 2Create an automation in the portal or ask Notis conversationally.
  • 3Tell Notis in one instruction to mark an invitee as a no-show only when a channel message confirms the absence and identifies the valid invitee uri and event.
  • 4Select the Slack channel message trigger and choose where reports should appear.
  • 5Test with a real, confirmed case and verify the Calendly record.

Questions about this workflow

What does this action require?

It requires the existing valid uri of the invitee for the scheduled event.

Should uncertain attendance be recorded?

No. Keep the instruction limited to messages that clearly confirm the invitee did not attend.
