Review community groups when a Slack signal changes

When a team removes a follow-up reaction, Notis can bring Heartbeat's group list into view to help clarify the community context around the change.

Trigger

Message Reaction Removed

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

Action

List Groups

Tool to retrieve a paginated list of access groups in the community. Use when you need to browse groups with optional filters for parent groups or user membership. Supports cursor-based pagination.

Why this helps

Changing or withdrawn signals can leave a team unsure which community structure to check next.

  • Makes a reaction change a consistent prompt to review group information.
  • Helps founders regain context without manually navigating Heartbeat.
  • Supports a clearer handoff when a team changes its follow-up signal.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Heartbeat to Notis once through the portal.
  • 2Create an automation in the portal, or tell Notis the intended outcome in plain language.
  • 3In one instruction, ask Notis to list Heartbeat groups when the designated Slack reaction is removed and summarize relevant access groups.
  • 4Select the Slack Message Reaction Removed trigger, optionally specify its channel or emoji, and choose a channel for run reports.
  • 5Test by removing the agreed reaction from a real message and reviewing the group summary.

Questions about this workflow

Does removing the reaction change any Heartbeat access?

No. The Heartbeat action lists groups; it does not modify memberships or access.

Can the trigger use a particular emoji?

The Slack reaction-removed trigger supports optional filtering by channel and emoji name.
