Check a host's busy times when WhatsApp scheduling comes up
See the host's busy intervals for the requested period and use that context to keep scheduling moving.
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
List user busy times
Fetches a user's busy time intervals (internal and external calendar events) in ascending order for a period up to 7 days; keyset pagination is not supported.
Why this helps
Availability coordination becomes slow when busy calendar windows are checked by hand across tools.
- See internal and external busy intervals for a user.
- Focus the check on a period of up to seven days.
- Reduce manual calendar review during scheduling.
Setup
Build it in a few focused steps.
- 1Connect WhatsApp and Calendly once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name and prompt.
- 3Describe the outcome: for a WhatsApp scheduling request, retrieve the specified user's busy times for the requested period of up to seven days and summarize them.
- 4Pick the New Message Received trigger and choose where run reports should go.
- 5Test with one real request that identifies the user and a valid date range.
Questions about this workflow
Are busy times the same as bookable slots?
No. Busy intervals show calendar conflicts. Use Calendly event type available times to retrieve actual bookable slots.
Can I check more than seven days?
This action supports a period up to seven days. Break a broader request into separate checks if needed.
What does the lookup require?
It needs the user and a time period. The prompt should clarify the time zone and range when the contact's message is ambiguous.

Supported Triggers and Actions
Notis builds workflows that link Whatsapp to Calendly. A trigger fires from one place; an action lands in another.
Whatsapp triggers
Calendly actions
Recurring trigger
Notis starts this workflow on a schedule, such as daily, weekly, or during business hours.
Cancel event
Permanently cancels an existing, active scheduled event by its `uuid`, optionally providing a `reason`, which may trigger notifications to invitees.
Webhook trigger
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Create an invitee no-show
Marks an invitee, identified by their existing and valid uri, as a 'no show' for a scheduled event.
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
