Sync removed Slack reactions to Discord
Keep status signals accurate as decisions change.
Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
Delete user reaction on message
Removes the authenticated user's own emoji reaction, which they must have previously added, from a specific message in a discord channel; this action is irreversible and cannot remove others' reactions.
Why this helps
Old Discord reactions make withdrawn approvals look current.
- Prevent stale approvals
- Keep shared context accurate
- Make reversals visible
Setup
Build it in a few focused steps.
- 1Connect Slackbot and Discordbot once in the Notis portal.
- 2Create an automation that identifies the related Discord message and removes the authenticated user's matching reaction.
- 3Pick Message Reaction Removed as the trigger.
- 4Choose a report channel and test with one real reversal.
Questions about this workflow
Can this remove someone else's reaction?
No. This action removes the authenticated user's own reaction only.
Can Notis announce the reversal too?
Yes. Ask it to post a short reversal note after removing the reaction.

Discordbot actions

Assign role to guild member
Assigns a role to a guild member, provided the bot has 'manage roles' permission in the guild and the role to be assigned is hierarchically lower than the bot's highest role.
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.

Adds an emoji reaction from the authenticated user/bot to a specific message in a discord channel; does not return information about existing reactions.
Direct Message Received
Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.
Add or update thread member
Adds a user to a specific, unarchived thread; the user must have access to the thread's parent channel, and for private threads, the bot must already be a member.
