Why this helps
A team may agree on a check in Slack but leave its formal record incomplete after the conversation moves on.
- Make a deliberate reaction useful as a review completion signal.
- Reduce manual copying of confirmed outcomes.
- Keep the validation record beside the document.
Setup
Build it in a few focused steps.
- 1Connect Slack and Affinda to Notis once through the portal.
- 2Create the automation in the portal or ask Notis conversationally to record document sign-offs.
- 3Write one plain-language instruction describing which agreed reaction represents a confirmed outcome and how to identify the document.
- 4Pick the message reaction added trigger and choose a channel for run reports.
- 5Test by adding the agreed reaction to one real document review message.
Questions about this workflow
Can the trigger filter by reaction?
The event supports optional filtering by channel and emoji name; choose the intended reaction when setting up the trigger.
What if the message does not identify a document?
The instruction should have Notis skip the action when it cannot confidently identify the document and outcome.
