Check open Calendly times when a contact asks in WhatsApp
Answer availability questions with a current look at open Calendly slots for the requested meeting window.
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 event type available times
Fetches available time slots for a calendly event type within a specified time range; results are not paginated.
Why this helps
Checking calendars manually interrupts conversations and risks offering times that are already taken.
- Respond to time questions with a current availability lookup.
- Avoid switching between chat and calendar pages.
- Focus the search on the event type and range the contact requested.
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 request for times, check available slots for the specified Calendly event type and requested future range, and summarize the options.
- 4Pick the New Message Received trigger and choose where run reports should go.
- 5Test with one real request that includes a clear event type and time range.
Questions about this workflow
Does this reserve a time slot?
No. This action retrieves available times. The contact still needs to book through Calendly.
How long can the requested time range be?
The Calendly action returns availability for the supplied range. Provide a reasonable future window and an existing event type.
What if the message does not name an event type?
Specify a default event type in your instruction or have Notis ask which meeting they mean.

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
