- Keep attendance checks tied to the session the requester named.
- Summarize the returned list for a faster review.
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Demio once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis to recognize participant-list requests, confirm the Demio event date, and summarize only the participants returned for that date.
- 4Pick the WhatsApp New Message Received trigger and choose where run reports go.
- 5Test with one real request containing a confirmed event date.
Questions about this workflow
Can it retrieve participants for every date automatically?
This action lists participants for a specific event date. The request or supplied context must identify that date.
Can it answer if the event date is unclear?
It should request or flag the missing date rather than use an assumed session.

Message Status Updated
Triggers when a WhatsApp message status changes. IMPORTANT LIMITATION: WhatsApp Cloud API does not provide a native polling endpoint for message status. Status updates are ONLY delivered via webhooks in real-time. This trigger cannot directly poll the WhatsApp API for status updates. This trigger will return empty results as WhatsApp does not support this operation. To track message status updates, you must: 1. Set up a webhook endpoint to receive status notifications from WhatsApp 2. Store the webhook data in your own database 3. Use a different mechanism to query your stored webhook data For more information, see: - https://developers.facebook.com/docs/whatsapp/cloud-api/webhooks
