- Respond immediately after approval
- Keep messages grounded in source content
- Reduce manual handoffs
Setup
Build it in a few focused steps.

- 2Create an automation named Webhook approval letter.
- 3Tell Notis to use the webhook and supplied Google Docs context to draft the approval letter, verify recipient and PDF details, and send after confirmation.
- 4Choose an HTTP webhook trigger and choose where run reports go.
- 5Test with one approved event.
