Reach the next attendee when space opens
Turn a newly available place into a clear, timely invitation.
Trigger
Webhook received
Notis starts this workflow when an external tool or custom backend sends an HTTP request.
Action
Send message
Send a text message to a whatsapp number. note: the message will reflect on the recipient's phone number only if they have texted first.
Why this helps
Open places go unfilled when waitlist outreach depends on noticing the change manually.
- Reduce vacant places
- Contact the next person promptly
- Make availability changes actionable
Setup
Build it in a few focused steps.
- 1Connect Eventbrite and WhatsApp to Notis.
- 2Describe the availability payload and invitation outcome in one prompt.
- 3Choose an incoming webhook and a run-report channel.
- 4Test with one real opening payload; require explicit recipient opt-in and authorization, and stop/report missing consent or recipient details.
