Why this helps
Review tasks can remain informal and easy to miss when the team has no clear signal that someone should pick them up.
- Give the team a lightweight way to mark a review as ready.
- Reduce follow-up messages about whether someone has started.
- Retrieve the current rules for the requested zone.
Setup
Build it in a few focused steps.
- 1Connect Slack and Cloudflare to Notis once through the portal.
- 2Create an automation in the portal, or ask Notis to retrieve firewall rules for a Slack review message with the agreed reaction.
- 3In one instruction, specify the reaction and require a clearly identified zone and review request.
- 4Select the Slack reaction-added trigger, optionally narrowed to the agreed emoji or channel, and choose a run-report channel.
- 5Test by reacting to one real review request for a known zone.
