Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Update Invoice
Tool to update an invoice. Use when you need to modify an existing invoice by its ID after retrieving its details.
Why this helps
An approval signal can be visible in Slack but absent from the invoice record that needs it.
- Record a clear approval signal with the invoice.
- Reduce the need to remember administrative follow-through.
- Make invoice status easier to review.
Setup
Build it in a few focused steps.
- 1Connect Slack and Firmao to Notis once through the portal.
- 2Create an automation in the portal or ask Notis to update an invoice after the agreed approval reaction is added.
- 3Describe the reaction's approval meaning and invoice identification rule in one prompt.
- 4Select the Slack Message Reaction Added trigger and a run-report channel.
- 5Test with the agreed reaction on a real message that identifies an invoice.
Questions about this workflow
Can the reaction indicate approval by itself?
Use a consistent reaction that your team has explicitly agreed means approval, and state that meaning in the prompt.
Does the workflow approve or pay the invoice externally?
It updates the existing Firmao invoice record; it does not perform an external payment.
