Why this helps
After a team agrees on a time in chat, the final scheduling step can still get lost in the scrollback.
- Give the team a simple signal that the details are ready.
- Avoid creating requests while a meeting is still being discussed.
- Move an agreed plan into Calendarhero promptly.
Setup
Build it in a few focused steps.
- 1Connect Slack and Calendarhero to Notis once through the portal.
- 2Create an automation with a plain-language instruction to create a request only when the chosen reaction marks a message with agreed, complete meeting details.
- 3Select Message Reaction Added and choose a channel for run reports.
- 4Test by reacting to one real message with confirmed participants and timing.
Questions about this workflow
Can the reaction alone provide meeting details?
No. The reacted-to message or its conversation needs to contain the participants, timing, and purpose.
Can I choose which reaction means ready?
Describe the intended reaction in the plain-language instruction and use it consistently.
