Raise a board blocker with one reaction
Give your team a simple way to surface a stuck task without writing a separate board update.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Set card block reason
Tool to block a Kanbanize card by setting a block reason. Use when you need to mark a card as blocked and specify the reason preventing progress.
Why this helps
Explaining the same urgent obstacle in chat and on the board adds steps when attention is already stretched.
- Turns a consistent reaction into a visible signal
- Reduces duplicate status updates
- Helps the team spot blocked work sooner
Setup
Build it in a few focused steps.
- 1Connect Slack and Kanbanize to Notis once through the portal.
- 2Create an automation with one instruction to set a block reason on the relevant card when the agreed red-flag reaction marks a blocker message.
- 3Select Message Reaction Added as the trigger.
- 4Choose a run-report channel and test with one real reaction on a blocked-work message.

Which reaction should we use?
Choose a reaction your team already uses consistently for blockers and name it in the plain-language instruction.
