Look up Cal bookings from WhatsApp inquiries
Get the booking context you need while the customer is still waiting. Send an inbound WhatsApp question to Cal, then review matching booking details for your reply.
Trigger
New Message Received
Triggered in real time when your WhatsApp Business number receives an inbound message from a customer (text, media, location, or contact). Delivered via the Cloud API webhook.
Action
Fetch all bookings
Fetches a list of bookings, optionally filtered by status, attendee, date range, or by event/team ids (which must belong to/include the authenticated user respectively), with support for pagination and sorting.
Why this helps
Searching Cal by hand interrupts conversations and makes it easier to overlook a meeting the customer is asking about.
- Review bookings without switching apps to search manually.
- Use a customer's message as the starting point for booking research.
- Reduce delays when answering meeting questions.
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Cal once in the Notis portal.
- 2Create an automation in the portal or tell Notis to create it from any channel.
- 3Describe the outcome: use each inbound WhatsApp inquiry to fetch relevant Cal bookings for review.
- 4Pick New Message Received as the trigger and choose where run reports should go.
- 5Test with one real inquiry that includes a customer or date detail.
Questions about this workflow
Does this workflow reply to the customer?
No. It fetches Cal bookings for review. Sending a WhatsApp reply is not part of this workflow.
What if the message does not include a name or date?
Notis can only search meaningfully with details in the message or context you provide. Vague inquiries may not identify a matching booking.

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
