Send a message in Telegram when someone books a meeting in Calendly

What each client fills in

Telegram: Chat ID

For example -1001234567890 or @channel

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.

• Calendly

  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.

• Telegram

  In Telegram, message @BotFather → /newbot → copy the token. Add the bot to the client’s group, or have the client message it once.

After you install it

It lands switched off. The client’s checklist holds exactly this:

1. Connect the client’s Calendly, for “Someone books a meeting”
2. Connect the client’s Telegram, for “Send a message”
3. Fill in Telegram: Chat ID (For example -1001234567890 or @channel)
4. Confirm with the client: The client’s Calendly is on a paid plan (Standard, Teams or Enterprise): Calendly sends webhook events only on those.
