Every step, in order
When it happens in the first app, the step runs in the second, with the client’s own account.
- Someone cancels a meeting
- A booking canceled on the account’s Calendly, within seconds. A reschedule is a cancel and a new booking; skip those with the toggle.
- Post a message
- Post to a channel the app has been invited to.

What each client fills in
- Slack: Channel
- For example #leads or C0123456789
The accounts it needs
Each is the client’s own, stored encrypted and never copied between clients. Until one is added the client’s checklist shows it, and nothing runs.
In the client’s Calendly: Integrations & apps → API and webhooks → Personal access tokens → Generate new token, with the scopes scheduling_links:write (booking links) and, for the triggers, users:read, webhooks:read and webhooks:write. A token made before Calendly introduced scopes keeps full access.
In the client’s Slack: api.slack.com/apps → Create New App → OAuth & Permissions → add the chat:write scope (and channels:history, plus groups:history for a private channel, for the message trigger) → Install to Workspace → copy the Bot User OAuth Token. Invite the app to the channel.
After you install it
It lands switched off. The client’s checklist holds exactly this:
- Connect the client’s Calendly, for “Someone cancels a meeting”
- Connect the client’s Slack, for “Post a message”
- Fill in Slack: Channel (For example #leads or C0123456789)
- Confirm with the client: The client’s Calendly is on a paid plan (Standard, Teams or Enterprise): Calendly sends webhook events only on those.
