Halt Countdown processing with a Slack signal

Give an urgent, deliberate stop instruction a clear signal for pausing all Countdown collection activity.

Trigger

Message Reaction Added

Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.

Action

Stop All Collections

Tool to stop all collections. Use when you need to halt any running or queued collections after reviewing operations.

Why this helps

During an operational issue, manually locating and stopping multiple runs can add stress and delay.

  • Provide a deliberate signal for a broad processing halt.
  • Reduce manual work during an operational interruption.
  • Keep the request and the response visible to the team.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Countdown api to Notis once in the portal.
  • 2Create an automation prompt that uses the agreed reaction to stop all collections only when the message clearly requests a broad operational halt.
  • 3Choose the Slack reaction added trigger, select a run-report channel, and test the prompt without triggering a live halt.

Questions about this workflow

Does the reaction always stop every collection?

The prompt should require clear context that a broad halt is intended; reserve the signal for that case.

Can a single collection be paused instead?

Yes. A separate automation using the single collection stop action can handle targeted pauses.
