Use a Slack reaction to check vouchers
Let a simple reaction mark a voucher list request for follow-up, without another reminder or task handoff.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
List Vouchers
Tool to list the resource owner's vouchers across all locations. Use when you need to retrieve vouchers with optional filtering, sorting, or pagination.
Why this helps
A request can be acknowledged in Slack but still require someone to remember to look up the voucher list later.
- Turns a reaction into a clear follow-up signal.
- Retrieves vouchers for review without a separate manual lookup.
- Helps keep acknowledged requests from becoming dropped balls.
Setup
Build it in a few focused steps.
- 1Connect Slack and Hotspotsystem to Notis once in the portal.
- 2Create an automation in the portal, or ask Notis to retrieve the HotspotSystem voucher list when a chosen reaction is added to a voucher-check request.
- 3Choose Message Reaction Added as the trigger and select a channel for run reports.
- 4Test by reacting to a real voucher-check request.
Questions about this workflow
Does the reaction create a voucher?
