Share Attendee Contacts Automatically on WhatsApp
When a meeting is 5 minutes away, Notis sends attendees each other's WhatsApp contact info so nobody has to ask 'What's your number?' before calling.
Trigger
Event Starting Soon
Triggers when a calendar event is within a configured number of minutes from starting. Returns event details, time remaining, attendees, and join links when available.
Action
Send contacts
Send contacts whatsapp number. note: the message will be delivered to the recipient only if they have initiated a conversation first.
Why this helps
Someone's running late and needs to call, but you realize nobody has each other's number and you're scrambling to share it.
- Removes friction: attendees can call or text each other without asking for numbers
- Handles late arrivals: if someone's running behind, they can message the group directly
- Professional: contact sharing happens automatically, not as an afterthought
Setup
Build it in a few focused steps.
- 1Connect Google Calendar and WhatsApp business accounts to Notis.
- 2Create a new automation: 'When a calendar event is 5 minutes away, send all attendees a WhatsApp message with each other's contact information.'
- 3Set the trigger to 'Event Starting Soon'.
- 4Choose your run-report channel.
- 5Test with a real meeting and confirm attendees receive contact details just before the event.
Questions about this workflow
Does this send phone numbers or WhatsApp profiles?
Notis can send WhatsApp contact cards with phone numbers. Recipients can add them to their contacts or message directly.
What if some attendees don't want their number shared?
You can set up a rule like 'Only share numbers for people on my internal team' or exclude specific attendees.
Will internal team members also get contact cards from each other?
By default, yes. You can filter it—e.g., 'Only share external attendees' contacts, not internal team members.'
