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Changing or withdrawn signals can leave a team unsure which community structure to check next.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