- Review multi-topic audio more systematically.
- Use the transcript and detected topics to prepare a follow-up.

Questions about this workflow
Does topic detection work on WhatsApp text messages?
No. This action analyzes audio, so the incoming message must provide a publicly accessible audio URL.
Can I use a WhatsApp media URL that requires login?
The audio URL must be publicly accessible to Deepgram. If it requires WhatsApp authentication, provide an accessible URL instead.

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
