Make a Slack approval reaction count
A consistent reaction can move an existing Knack item forward without a separate manual status 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
Update object record
Tool to update an existing record in a specific Knack object. Use when you need to modify field values in an existing record. Only fields provided in the request will be updated; all other fields remain unchanged.
Why this helps
Approvals happen in Slack, while the tracker remains stale until someone remembers to update it.
- Keep approved items from waiting on a second update.
- Reduce status drift between discussion and tracking.
- Use a familiar team signal to maintain the record.
Setup
Build it in a few focused steps.
- 1Connect Slack and Knack to Notis once through the portal.
- 2Create an automation prompt explaining which reaction means approval and how Notis should identify and update the matching Knack record.
- 3Select Slack Message Reaction Added and choose a channel for run reports.
- 4Test with a real eligible message and confirm the intended record changed.
Questions about this workflow
Can any reaction mark approval?
Use a consistent, unambiguous emoji and name it in the prompt.
What if the matching Knack record is unclear?
Tell Notis to update a record only when it can confidently identify the match.
