Make Calendly cancellations visible in Slack

Let the team know when a meeting is cancelled, with a short update based on the cancellation information received.

Trigger

Webhook received

Notis starts this workflow when an external tool or custom backend sends an HTTP request.

Action

Post message to channel

Deprecated: posts a message to a slack channel, direct message, or private channel. use `send message` instead.

Why this helps

A cancelled meeting can leave teammates working from an outdated plan if the change stays in Calendly.

  • Surface schedule changes where the team coordinates
  • Reduce outdated meeting assumptions
  • Share only the cancellation details present in the webhook

Setup

Build it in a few focused steps.

  • 1Connect Calendly and Slack once in the Notis portal.
  • 2Create an automation in Automations, then choose New Automation.
  • 3Tell Notis to post a short Slack update when it receives a Calendly cancellation request, using only details included in that request.
  • 4Choose the Notis webhook trigger and select where run reports should go.
  • 5Test with one real cancellation webhook and review the Slack message.

Questions about this workflow

Can this detect a cancellation without a webhook request?

No. The workflow starts when a Notis webhook request is received.

Will it know why the meeting was cancelled?

Only if the reason is included in the webhook data.
