Notis

Correct Calendly attendance records from Slack

If a teammate confirms that someone did attend, Notis can remove the mistaken no-show record so the record reflects the correction.

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

Delete invitee no show

Deletes an invitee no-show record by its `uuid` to reverse an invitee's 'no-show' status; the `uuid` must refer to an existing record.

Why this helps

A mistaken attendance status can linger when correcting it requires revisiting a finished meeting.

  • Correct a confirmed attendance error while context is available.
  • Reduce lingering admin about a past meeting.
  • Keep the change tied to an identified record.

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.
  • 3Use one instruction asking Notis to delete a no-show record only when a channel message confirms it was incorrect and supplies the record uuid.
  • 4Choose the Slack channel message trigger and a channel for run reports.
  • 5Test with a real correction request for an identified record.

Questions about this workflow

What identifier is needed?

The uuid must refer to an existing Calendly invitee no-show record.

Can this mark someone as attended?

It deletes the no-show record; it does not create a separate attendance status.
