Collect a quick response on a PDF review
Give reviewers a simple choice when a document is ready for approval.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Send interactive buttons
Send an interactive button message to a whatsapp number. button messages allow users to quickly respond by tapping up to 3 predefined buttons. perfect for yes/no questions, quick choices, or call-to-action scenarios. note: the message will be delivered to the recipient only if they have texted first.
Why this helps
