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.
