Example Use Case

​
Scenario: Auto‑callback for Appointment Booking

A CRM sends booking details via webhook: 
{
  "name": "Amit",
  "phone_number": "918765432101",
  "appointment_slot": "Today at 4 PM"
}
Your Journey contains this action:
  • Phone Number → {{inbound_webhook.phone_number}}
  • Voice AI Agent → Appointment booking agent
The AI Agent calls the customer automatically to:
  • Confirm the appointment
  • Reschedule if needed
  • Capture additional info
