# How to Get Notified on Slack When an Event is Booked?

> Connect Cal ID to Slack through Zapier, Pabbly, Make, or ViaSocket to receive instant booking notifications in the channels where your team works.

Stay on top of your schedule by getting instant alerts where you already work. By connecting **Cal ID** to **Slack** via **Zapier**, **Pabbly**, **Make** or **ViaSocket** you can stop checking your email and get notified the moment a booking happens.

### Why use this?

* **Instant Alerts:** Know immediately when a new client books you.
* **Team Sync:** Send notifications to a shared channel so your team stays updated.
* **All-in-One Place:** Track new bookings, reschedules, and cancellations without leaving Slack.

<Info>
  To post into a channel, your automation tool (Zapier, Pabbly, Make, or ViaSocket) needs permission to your Slack workspace. When you connect Slack, you'll be asked to authorize it — if you want alerts in a private or shared channel, make sure you have permission to add apps to that workspace, or ask a Slack workspace admin to approve the connection.
