Confirm task visibility after acknowledgment
Pair a clear acknowledgment signal with a watcher check so the team can tell whether the relevant person follows the card.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Check User Is Card Watcher
Tool to check if a user is a watcher of a specific card. Use when you need to verify if a user is watching a card.
Why this helps
A reaction shows someone noticed a message, but it does not confirm they can follow the task's board updates.
- Separates message acknowledgment from ongoing task visibility
- Clarifies whether a collaborator watches the card
- Reduces follow-up uncertainty
Setup
Build it in a few focused steps.
- 1Connect Slack and Kanbanize to Notis once through the portal.
- 2Create an automation with a single instruction to check the relevant collaborator's watcher status when the agreed acknowledgment reaction appears on a task update.
- 3Select Message Reaction Added as the trigger.
- 4Choose a channel for run reports and test with one real acknowledgment.
Questions about this workflow
Does the reaction itself make the person a watcher?
No. The action checks watcher status and does not change it.
What reaction should trigger the check?
Use a reaction your team consistently treats as an acknowledgment and describe it in the instruction.
