Why this helps
A quick tap can be easy to forget when several approvals are waiting in chat.
- Create a readable record of a button-based approval.
- Make decisions easier to confirm later.
- Reduce manual note-taking after a quick response.

- 2Create an automation and describe the approval receipt in one plain-language prompt.
- 3Choose Callback Query Received as the trigger and select a channel for run reports.
- 4Tap an approval button in a real test and inspect the PDF.
Questions about this workflow
What counts as an approval?
Use an inline button whose label or context indicates approval, and describe how Notis should treat that response.
Does this verify the approver's identity externally?
It creates a PDF from the callback event details available to the workflow; it does not provide separate identity verification.
