Use a Slack reaction to close an invoice status loop
Mark a clear status decision for follow-through. Notis can use the surrounding message to identify the invoice and apply the confirmed update in Chaser.
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 existing invoice's information using its unique identifier. use after confirming the invoice exists when you need to modify fields like status, amounts, or dates.
Why this helps
Status decisions can be acknowledged with a reaction but still not make it into the invoice system.
- Make a deliberate reaction an actionable reminder.
- Connect an agreed status decision to Chaser.
- Leave uncertain status changes for clarification.
Setup
Build it in a few focused steps.
- 1Connect Slack and Chaser to Notis once through the portal.
- 2Create an automation in the portal or ask Notis conversationally, directing it to update an invoice status only when the reacted-to message confirms the change and identifies the invoice.
- 3Pick Message Reaction Added as the trigger and choose a channel for run reports.
- 4Test with one real, confirmed status change and verify the invoice.
Questions about this workflow
Does the reaction itself indicate a particular status?
No. The prompt should specify the reaction's intent and require the message context to state the actual confirmed change.
What if the message asks for a status check only?
Have Notis report the existing information for review and avoid an update unless a change is clearly requested.
