Turn Slack no-show updates into rebooking calls
A missed appointment in Slack can prompt a calm, consistent call to help the customer find another time.

Action
Make a phone call from agent

Why this helps
Rebooking follow-up is easy to postpone when the missed appointment is only noted in a team channel.
- Give customers a prompt chance to reschedule.
- Reduce the number of reminders your team must hold in mind.
- Keep the follow-up approach consistent across missed appointments.
Setup
Build it in a few focused steps.
- 1Connect Slack and Bolna to Notis once in the portal.
- 2Create an automation or tell Notis to call customers when a missed appointment is shared in Slack.
- 3Describe in one plain-language instruction how the agent should offer a rebooking conversation.
- 4Choose Slack's Channel Message Received trigger and select a channel for run reports.
- 5Test with one real no-show update and confirm the correct follow-up call is placed.
Questions about this workflow
Can the agent book a new time during the call?
The call follows the behavior and capabilities of your configured Bolna agent; describe the rebooking goal in the instruction.
How do I avoid calling for unrelated updates?
Tell Notis what a qualifying missed-appointment message looks like in the automation instruction.
