Keep trust access aligned when an approval is withdrawn
If the team's approval signal is removed, prompt a deliberate check and revoke the corresponding authorization when appropriate.
Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
Patch authorization
Tool to update or revoke an existing authorization. Use when managing authorization access groups or revoking access.
Why this helps
A withdrawn approval can leave access active if nobody remembers to revisit the authorization.
- Connects a changed team decision to an access follow-up.
- Helps prevent stale access from being overlooked.
- Keeps the revocation condition explicit and reviewable.
Setup
Build it in a few focused steps.
- 1Connect Slack and Conveyor to Notis once in the portal.
- 2Create an automation in the portal or describe how a withdrawn approval should affect access.
- 3In one instruction, specify the approval emoji and require a clear matching authorization and a valid revocation reason before patching access.
- 4Select Message Reaction Removed and choose a channel for run reports.
- 5Test with a controlled example and verify that only the matching authorization is affected.
Questions about this workflow
Does reaction removal always mean revoke access?
Only configure that interpretation if it matches your team's process. The instruction should require clear request and authorization context.
What does the action do?
It patches an existing authorization, which can be used to revoke access when the authorization is identified.
