Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Get Working Times
Tool to retrieve working times for a specific calendar. Use when confirming available time slots before booking appointments.
Why this helps
A simple availability question can turn into a distracting round trip through calendars and chat.
- Keeps the availability check close to the request.
- Cuts down on manual calendar lookups.
- Makes it easier to respond before a scheduling thread goes cold.
Setup
Build it in a few focused steps.
- 1Connect Slack and eTermin to Notis once in the portal.
- 2Create an automation in the portal or ask Notis conversationally.
- 3Write one instruction asking Notis to check the relevant eTermin calendar's working times for clear Slack availability questions and report the result.
- 4Choose the Slack Channel Message Received trigger and a channel for run reports.
- 5Test with a real message that names a calendar and requested time.
Questions about this workflow
Does this book the appointment?
No. This workflow checks working times and reports availability; it does not create an appointment.
What if the message does not name a calendar?
Have the instruction ask Notis to report that the calendar is unclear instead of guessing.
