Mark a message for privacy cleanup with one reaction
When you add your chosen reaction to a Slack message, have Notis anonymize sensitive strings from that message using Anonyflow.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Anonymize Value
Tool to anonymize a string or array of string values. use when you need to conceal sensitive text before storage or transmission. example: `anonymizevalue().execute(anonymizevaluerequest(data=['secret']))` limitations: only supports list of strings, not nested structures.
Why this helps
Remembering which message needs privacy cleanup creates another follow-up task after the conversation has moved on.
- Use a visible reaction as a low-effort review cue.
- Reduce the chance that a flagged message is forgotten.
- Keep the privacy action tied to the message that prompted it.
Setup
Build it in a few focused steps.
- 1Connect Slack and Anonyflow to Notis once through the portal.
- 2Create an automation in the portal or ask Notis for a reaction-based workflow.
- 3Give Notis one instruction to anonymize sensitive strings in the message when your selected reaction is added.
- 4Choose Message Reaction Added and specify the intended channel and emoji in your instruction if needed.
- 5Test by adding the reaction to a message with fictional sensitive values.
Questions about this workflow
Can the trigger filter by emoji?
The supplied trigger supports optional filtering by channel and emoji name. Select the trigger and describe the intended cue in your automation setup.
Will reacting edit the original post?
No. Anonymize Value processes string values; it does not modify the original Slack message.
