Use Emoji to Mark Issue Progress in Slack

When a Linear issue moves to 'In Progress' or 'Done', an emoji reaction appears on the Slack message. Your team sees workflow progress visually.

Trigger

Public Team Issue Properties Updated

Fires when properties on a *public-team* Linear issue change (status, assignee, priority, labels, etc.). For private teams (lock icon in Linear's sidebar) use `LINEAR_PRIVATE_TEAM_ISSUE_PROPERTIES_UPDATED`.

Add reaction to message

Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.

Why this helps

Neurodivergent founders often prefer visual cues over reading text. Emoji reactions on Slack are quick visual markers that reduce cognitive load compared to reading full status descriptions.

  • Emoji reactions provide instant visual feedback on issue progress
  • Reduce cognitive load with visual markers instead of text-heavy updates
  • Team quickly understands workflow status at a glance

Setup

Build it in a few focused steps.

  • 1Connect Linear and Slack to Notis.
  • 2Ask Notis: 'When a Linear issue status changes to in progress, add a :hourglass: emoji reaction to the original Slack message. When it's done, add a :checkmark: reaction.'
  • 3Select 'Public Team Issue Properties Updated' as the trigger (or Private Team version).
  • 4Designate your Slack channel for run reports.
  • 5Update a Linear issue's status and watch the emoji reaction appear on the corresponding Slack message.

Questions about this workflow

Can I use custom emoji?

Absolutely. Tell Notis which emoji you prefer for each status (e.g., ':gear_spinning: for in progress, :tada: for done').

What if the Slack message is old?

Notis reacts to the most recent message mentioning that issue in Slack.
