Save invoice reviews with a reaction
Mark an invoice discussion for review with a reaction, and Notis can gather the relevant Finmei records as a follow-up.
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 Invoices
Tool to list invoices. Use when you need a paginated list of invoices with basic details.
Why this helps
A useful billing thread can scroll away before you have time to review the invoice.
- Capture review intent without composing another message.
- Gather records while the conversation context is available.
- Create a repeatable cue for invoice follow-up.
Setup
Build it in a few focused steps.
- 1Connect Slack and Finmei to Notis once in the portal.
- 2Create an automation in Automations or ask Notis conversationally.
- 3Tell Notis that the selected reaction on an invoice-related message should prompt a relevant Finmei invoice search and a concise review summary.
- 4Choose the Slack reaction-added trigger and a report channel.
- 5Test with the reaction on a message that identifies a known invoice.
Questions about this workflow
Does adding the reaction approve the invoice?
No. It only prompts a lookup for review.
Can the workflow find invoices without a reference?
It may use the message context, but should flag uncertainty rather than assume a match.
