Use a reaction to check a company's Affinity lists
When a company comes up in Slack, use a reaction to request a quick check of its existing Affinity list membership.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Get a company s lists
Returns metadata for all the lists on which the given company appears.
Why this helps
It takes extra effort to remember whether a company is already tracked and which list contains its details, especially during a busy discussion.
- Request a company-list check without adding another message.
- Reduce uncertainty about existing relationship tracking.
- Make a small lookup easy to trigger at the right moment.
Setup
Build it in a few focused steps.
- 1Connect Slack and Affinity to Notis once in the portal.
- 2Create an automation in the portal or ask Notis to check Affinity lists for a company when a chosen Slack reaction is added.
- 3Describe in one plain-language instruction how Notis should identify the company and report its list membership.
- 4Select the Slack reaction-added trigger, choose a report channel, and test with a real company message.

Can this trigger only on a specific emoji?
Yes. The Slack reaction-added trigger supports optional emoji and channel filters.
Does it read details from each list?
