Respond to Meeting Requests With Instant Availability
A customer messages asking for a meeting. Notis checks your calendar, finds your free slots, and you can respond immediately with available times, right there in WhatsApp.
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
Find free slots
Finds free/busy time slots in google calendars for specified calendars within a defined time range (defaults to the current day utc if `time min`/`time max` are omitted), enhancing busy intervals with event details; `time min` must precede `time max` if both are provided.
Why this helps
When someone asks for a meeting, neurodivergent founders often pause to mentally review their calendar, leading to slow responses and a reputation for being unreliable. The cognitive load of juggling two apps (WhatsApp + Calendar) makes it hard to respond quickly and confidently.
- Respond to meeting requests immediately without context-switching
- Reduce double-booking anxiety by confirming availability
- Look responsive and organized to clients
- Minimize decision fatigue by automating the lookup
Setup
Build it in a few focused steps.
- 1Connect WhatsApp Business Account and Google Calendar to Notis.
- 2Create an automation named 'Availability Check on Message', set Trigger to 'New Message Received' from WhatsApp.
- 3Configure Notis with: 'When someone asks about meeting times (phrases like "Can we meet?", "When are you free?", "Let's schedule a call"), check my Google Calendar for free slots in the next 7 days and note them.'
- 4Set the reporting channel and test time zone settings.
- 5Send yourself a test message like 'When are you available for a quick call this week?' and check that Notis identifies free slots.
Questions about this workflow
Can I limit the search to business hours only?
Yes, you can specify in the prompt: 'Check availability only during 9am-5pm EST, Monday through Friday.'
What if I want to exclude certain calendars?
You can tell Notis which calendar to check (primary, or a specific named calendar). This lets you ignore personal events and focus on work availability.
How far ahead should it look?
You decide. The prompt can say '7 days ahead', '14 days ahead', or 'next 30 days'. Choose what makes sense for your booking window.

Supported Triggers and Actions
Notis builds workflows that link Whatsapp to Google Calendar. A trigger fires from one place; an action lands in another.
Whatsapp triggers
Google Calendar actions
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
