Notis

Archive Slack channels from Discord reactions

A Discord thread gets a checkmark reaction—the discussion is done. Notis immediately archives the corresponding Slack channel, freeing you from manual cleanup and keeping your workspace lean and focused.

Trigger

Message Reaction Added

Triggered when a reaction (emoji) is added to a message in a monitored Discord channel.

Action

Archive a Slack conversation

Archives a slack conversation by its id, rendering it read-only and hidden while retaining history, ideal for cleaning up inactive channels; be aware that some channels (like #general or certain dms) cannot be archived and this may impact connected integrations.

Why this helps

Dead projects clutter your Slack workspace; archiving them manually is tedious, and the workspace becomes harder to navigate as it grows.

  • Keep Slack workspace clean and organized automatically
  • Signal project completion across platforms
  • Reduce cognitive load from navigating cluttered workspaces
  • Build automated cleanup workflows

Setup

Build it in a few focused steps.

  • 1Connect Discord and Slack to Notis
  • 2Create a new automation with the prompt: 'When a Discord message gets a checkmark reaction, archive the corresponding Slack channel'
  • 3Choose the trigger: Message Reaction Added from your Discord channel
  • 4Select the Slack reporting channel
  • 5Test by adding a checkmark reaction to a Discord message and verify the Slack channel is archived

Questions about this workflow

Which emoji reactions trigger archival?

You specify in your prompt. Common ones are ✅ or 🎉, but you can use any emoji.

What if there's no corresponding Slack channel?

Notis skips the action gracefully. Your prompt can also handle this: 'notify me if no channel exists'.

Can I unarchive channels if the reaction is removed?

Yes. You can create a companion workflow that unarchives when the reaction is deleted.
