Task Discussion Visibility: Know When Tasks Get Commented
A comment just landed on a task in ClickUp. Slack gets a reaction added. The team sees there's discussion happening without needing a notification flood.
Trigger
Task Comment Posted
Triggers when a comment is added to a task. `changes[]` carries one `CommentChange` entry whose `comment` field is the typed `ClickupComment` object (id, text, user, reactions, etc.).
Action
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
Important task discussions happen in ClickUp comments but the team working in Slack has no idea, leading to duplicated discussion or missed context.
- See task activity without leaving Slack
- No message spam, just a small emoji indicator
- Team stays aware of discussions on their assigned work
- Reduce ClickUp-tab-switching for comment checks
Setup
Build it in a few focused steps.
- 1Connect ClickUp and Slack to Notis via the portal
- 2Create an automation: 'When a comment is posted on a task in ClickUp, add a reaction emoji in Slack'
- 3Choose which emoji signals comments (e.g. :speech_balloon: or :speech-balloon:)
- 4Select 'Task Comment Posted' as the trigger
- 5Post a test comment in ClickUp and watch the emoji reaction appear in Slack
Questions about this workflow
Where does the emoji appear?
In Slack threads or messages related to that task, making activity visible at a glance.
Can we use different emojis for different comment types?
Yes. You can ask Notis: 'Use :warning: if a comment mentions blockers, :white_check_mark: for approvals.'
Will this work with existing messages or only new ones?
It works best with tasks already linked to Slack messages. Notis will find the relevant thread and add the reaction.
