Slack Booking Notifications

Post every new LemCall booking into a Slack channel so the team sees inbound meetings as they land, without watching a shared inbox.

Sales and support teams live in Slack. Pushing bookings into a channel means the meeting is visible the moment it is made, not when someone next opens a calendar.

Key Takeaways

  • Slack connects in a few minutes from the Integrations screen.
  • Unlimited hosts on a flat workspace price, so coverage is not a licence decision.
  • Bookings are never metered, including on the free plan.

What the Slack integration does

  • Posts new bookings into the channel behind your Slack webhook.
  • Includes the booker, the meeting, the time and the confirmation number.
  • Announces cancellations, reschedules and received payments too.

Connecting it

  • Create an incoming webhook in Slack for the channel that should receive bookings.
  • In LemCall open Settings and paste the Slack webhook URL into Slack notifications.
  • Send the built-in test message to confirm it reaches the channel.
  • Take a test booking to check the formatting.

What it does not do

Worth knowing before you build a process around it, rather than after:

  • Posting is one-way; you cannot reschedule from Slack.
  • One Slack webhook per workspace, so bookings land in a single channel.
  • There is no per-meeting-type channel routing — use webhooks and Zapier for that.

What it costs

One flat price per workspace with unlimited hosts, so connecting more people is never a licence decision.

This integration is available on every plan, including the free one, which takes unlimited bookings with calendar sync and reminders.
