Approve and Complete Workflows With Slack Emoji

A workflow needs approval. Someone posts it in Slack. You react with :white_check_mark:. Notis marks the workflow complete. Approvals in seconds.

Trigger

Message Reaction Added

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

Action

Complete a workflow run

This tool marks an entire workflow run as completed in process street. it updates the workflow run's status to 'completed', distinguishing it from process street complete task which completes individual tasks.

Why this helps

Approval workflows are slow. People request approval in Slack but nobody remembers to actually approve it in Process Street. Work gets stuck waiting.

  • Approvals happen in Slack where conversations are happening
  • Workflows complete automatically once approved
  • Reduce bottlenecks in approval-gated work
  • Faster delivery due to instant approvals

Setup

Build it in a few focused steps.

  • 1Connect Slack and Process Street to Notis.
  • 2Create an automation with the prompt: 'When someone reacts to a Slack message with :white_check_mark:, mark the corresponding Process Street workflow as complete (approved).'
  • 3Choose 'Message Reaction Added' as your trigger and specify the emoji.
  • 4Configure which channels this applies to (or all channels).
  • 5Test by posting a workflow for approval and reacting with the emoji.

Questions about this workflow

Can I use different emojis for different approval types (e.g., :white_check_mark: to approve, :x: to reject)?

Yes. Set up multiple automations with different emojis triggering different actions (complete, update status, request changes, etc.).

What if multiple people react?

By default, the first reaction completes it. You can configure it to require multiple approvals (e.g., require 2 checkmarks) if needed.

Can I add approval notes when I react?

You can reply to the message with notes, and Notis will capture those and add them to the workflow before marking it complete.
