Use a reaction to check Demio dates

Mark schedule questions for a quick lookup with a reaction your team already uses.

Trigger

Message Reaction Added

Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.

Action

List Event Dates

Tool to list all scheduled session dates for a given Demio event. Use when you need the session schedule by event ID.

Why this helps

A schedule question can get buried before anyone checks the event calendar.

  • Create a lightweight cue for a date lookup.
  • Reduce the chance that an event question gets lost in channel traffic.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Demio to Notis once in the portal.
  • 2Create an automation in the portal, or ask Notis to create it in plain language.
  • 3In one instruction, say to retrieve session dates when a schedule-question message receives the chosen reaction.
  • 4Select the Slack Message Reaction Added trigger and choose a channel for run reports.
  • 5Test by reacting to a real message that identifies the Demio event.

Questions about this workflow

Does the reaction itself identify the event?

The instruction should explain the signal, and the event ID needs to be available for the date lookup.

Does this add dates to the event?

No. It retrieves scheduled dates.
