Generate invoice PDFs from Slack approval reactions
Make the approval signal the handoff into invoice production.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Create PDF Asynchronously
Tool to queue asynchronous PDF generation via webhook. Use when you need to generate a PDF in the background and receive the result via a webhook.
Why this helps
Approved invoices still wait when someone has to monitor reactions and submit the document manually.
- Shorten the approval to invoice gap
- Reduce missed finance handoffs
- Keep the request traceable in Slack
