Start a domain check with a Slack reaction
When a shared domain needs a closer look, react to its message and get registration details for the next step.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Domain WHOIS Lookup
Tool to retrieve WHOIS information for a given domain. Use when you need domain registration and contact details via IP2WHOIS API.
Why this helps
Quick due-diligence requests can fall through when nobody owns the extra lookup task.
- Makes a domain check easy to request
- Connects research to the message that prompted it
- Keeps registration details in a Notis run report
Setup
Build it in a few focused steps.
- 1Connect Slack and Ip2location io once in Notis.
- 2Create an automation through Automations, or ask Notis conversationally for a reaction-based domain check.
- 3Give Notis one plain-language instruction to find a domain in the reacted-to message and retrieve WHOIS information.
- 4Choose Message Reaction Added, set an optional emoji or channel filter, and select a run-report channel.
- 5Test by reacting to a real Slack message that includes a domain.
Questions about this workflow
Can a reaction request WHOIS for an IP?
