Celebrate completed tasks with automatic Slack reactions
When someone marks a task done in Airtable, Notis reacts to the original Slack announcement with a checkmark or celebration emoji. Your team gets instant, visible feedback without hunting through Airtable.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Add reaction to message
Adds a specified emoji reaction to an existing message in a slack channel, identified by its timestamp; does not remove or retrieve reactions.
Why this helps
Tasks get completed in Airtable, but the Slack conversation never reflects that completion. People keep commenting assuming it's still in progress, creating confusion.
- Provide instant visual feedback on task completion
- Reduce confusion about what's actually done
- Keep Slack conversations automatically synchronized with Airtable reality
- Lower the friction to celebrate progress with your team
Setup
Build it in a few focused steps.
- 1Connect Airtable and Slack to Notis (one-time).
- 2Create an automation: 'When a task is marked complete in [Airtable table], find the task announcement in [Slack channel] and add a checkmark reaction.'
- 3Select 'Webhook' as the trigger to receive completion events.
- 4Tell Notis which emoji to use (default is checkmark, but you can choose celebration, star, etc.).
- 5Test by completing a task in Airtable and checking that the Slack message gets the reaction within seconds.
Questions about this workflow
What if the task wasn't announced in Slack yet?
Notis will skip the reaction but you can set up a separate automation to post the task to Slack first if you prefer.
Can I use different emojis for different statuses?
Yes. Create separate automations for each status (e.g., checkmark for done, clock emoji for in-progress, warning emoji for blocked).
Does this work for subtasks or only top-level tasks?
It works for any record type in Airtable, including nested tasks if your base structure supports them.
