Check Cal availability from a WhatsApp status event
When a scheduling message changes status, check Cal availability to prepare a useful next step for your conversation.
Trigger
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
Action
Check calendar availability
Retrieves free/busy availability for a specified calendar to aid scheduling without revealing event details; requires an existing, accessible calendar, noting that data granularity can vary.
Why this helps
Without a cue, it is easy to let a scheduling conversation stall after a message status changes.
- Use real-time status events as a cue for scheduling review.
- Check current free-busy data before suggesting an alternative.
- Reduce the effort of remembering to revisit open conversations.
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Cal once in the Notis portal.
- 2Create an automation through Automations, New Automation, or by describing it to Notis from any channel.
- 3Describe the outcome: when a WhatsApp status changes for a scheduling conversation, check the relevant Cal calendar's availability.
- 4Pick Message Status Updated as the trigger and choose a report destination.
- 5Test with one real status change and confirm the check uses the intended calendar and time context.
Questions about this workflow
How does the status trigger run?
It receives status updates through real-time WhatsApp Cloud API webhooks. It cannot poll WhatsApp for them.
Does a status update tell Cal which dates to check?
Not necessarily. Include a suitable time range or explain how to determine it from the available conversation context.
