Tag GitHub Issues with a Single Slack Emoji

You react with a checkmark in Slack—Notis instantly labels the issue as 'reviewed' in GitHub. No extra steps, just reactions.

Add labels to an issue

Adds labels (provided in the request body) to a repository issue; labels that do not already exist are created.

Why this helps

After discussing an issue in Slack, you forget to go back to GitHub and add the relevant labels. Your issue triage falls out of sync with your actual conversation.

  • Label issues without switching apps—just emoji react
  • Keep GitHub issues in sync with Slack conversations in real time
  • Your team naturally creates consistent issue labels through familiar emoji shortcuts

Setup

Build it in a few focused steps.

  • 1Connect Slack and GitHub integrations to Notis.
  • 2Create the automation by telling Notis: 'When I react to a message in Slack with a specific emoji, add the corresponding label to the linked GitHub issue.' Give examples of which emoji map to which labels (e.g., 'check' = 'reviewed', 'fire' = 'urgent').
  • 3Select the Slack channel where this should apply.
  • 4Choose your Notis notification channel.
  • 5Test by reacting to a message about a real GitHub issue—Notis will add the label and confirm.

Questions about this workflow

What emojis can I use?

Any emoji. You define the mapping when setting up the automation. Common ones: check for reviewed, fire for urgent, eyes for in-progress, wave for help-needed.

What if Slack doesn't mention which GitHub issue to label?

Notis looks for issue links or issue numbers in the conversation. If there's ambiguity, it asks in your Notis channel before applying labels.

Can different emoji mean different things in different channels?

You can set up multiple automations, each with its own emoji-to-label mappings for different channels or teams.
