Trigger
Message Reaction Removed
Triggered when a reaction is removed from a message in Slack. Supports optional filtering by channel and emoji name.
Action
IP2Location Get IP Geolocation

Why this helps
When review status changes, a team may close a thread without confirming the location context it needs.
- Recheck an address at a review-status change.
- Keep the latest lookup tied to the original message.
- Create a consistent follow-up cue for channel discussions.
Setup
Build it in a few focused steps.
- 1Connect Slack and Ip2location to Notis once.
- 2Create an automation and tell Notis in plain language to look up the IP in a message when its review reaction is removed.
- 3Select Message Reaction Removed and choose a channel for run reports.
- 4Test by removing the intended reaction from a real message containing an IP.
Questions about this workflow
Does removing a reaction guarantee that an IP has changed?
No. The event only signals that a reaction was removed; use the prompt to define why that change should lead to a fresh lookup.
Can the reaction event be scoped?
The reaction-removed event supports optional filtering by channel and emoji name.
