Interactive Buttons Sent Instantly When Meetings Are Created
Reduce email ping-pong: when a calendar invite lands, send WhatsApp buttons (Yes/No/Ask Later) so attendees confirm in seconds, not days.
Trigger
Event Created
Polling trigger that fires when a new calendar event is created. Returns event ID, summary, start/end times, and organizer info.
Action
Send interactive buttons
Send an interactive button message to a whatsapp number. button messages allow users to quickly respond by tapping up to 3 predefined buttons. perfect for yes/no questions, quick choices, or call-to-action scenarios. note: the message will be delivered to the recipient only if they have texted first.
Why this helps
Waiting days for people to RSVP to calendar invites because email sits unread, leaving you uncertain about headcount and prep needs.
- Faster RSVPs: interactive buttons get responses 3x faster than email
- Less cognitive overhead: you see confirmations stream in on WhatsApp, your main communication channel
- Attendee friendly: people tap a button instead of finding and opening their email client
Setup
Build it in a few focused steps.
- 1Make sure Google Calendar and WhatsApp business accounts are connected to Notis.
- 2Create a new automation with the prompt: 'When a new event is scheduled, send attendees a WhatsApp message with three buttons: Attending, Not Attending, Maybe.'
- 3Select 'Event Created' as your trigger.
- 4Pick the channel where Notis should report which messages were sent (WhatsApp, email, or Telegram).
- 5Test by scheduling a quick event with a colleague and watch the buttons appear in their WhatsApp inbox.
Questions about this workflow
Can I customize the button labels?
Yes, tell Notis exactly what labels you want. For instance, 'Send buttons labeled Ready, Reschedule, Double-booked' instead of the default Yes/No/Maybe.
Does the automation send buttons to all attendees or just external guests?
By default, it sends to all attendees. You can refine it to send only to people outside your organization, or exclude your team members.
What happens after someone taps a button?
Notis logs their response and can optionally send a follow-up message. You can also tell Notis to update their RSVP status in Google Calendar automatically.
