The 5-Minute Demo Script

Before you start: Pull up /api/demo/dashboard before the prospect joins. The bookings table and activity feed should show demo data already — makes the demo feel "alive" from the first second.
OPENER (30s) "Before I show you anything — what's your front desk team currently doing for booking calls? Are they taking calls all day?"
Transition (15s) "Let me show you what this looks like with an AI receptionist. Watch this — the patient just texted your WhatsApp Business number..."
Patient texts "Hi, I'd like to book a dental cleaning for tomorrow morning"
AI replies (point to response time) "Hi there! 👋 Welcome to Bright Smile Dental. I'd love to help you schedule a cleaning. What's your name, and what time works for you tomorrow?"
Point to: "Instant — 2 seconds. No staff involved. Patient didn't wait on hold."
Patient "It's Maria Garcia, 10am would be perfect"
AI confirms "✅ Booking confirmed!
Name: Maria Garcia
Date:
Time: 10:00 AM
📍 123 Wellness Blvd, Suite 100, Miami FL

See you there! I'll send a reminder 24 hours before. 😁"
Point to: "Booking saved, Google Calendar event created, confirmation sent. In 24 hours, the reminder fires automatically."
Objection: "What if the patient doesn't speak English?"
"The AI is multilingual — Arabic, French, and English. Dentists in North Africa and the Middle East list this as the #1 feature."
Objection: "What if the AI gives wrong info?"
"It only uses your clinic's real hours, services, and calendar availability. No invented times. Unclear situations route to your staff with the full conversation."
Close (30s): "That's the full flow — first message to confirmed booking, reminder 24 hours before, zero staff time. Setup takes under an hour. Most clinics see no-shows drop 30-40% in the first 3 months. Want me to walk you through pricing?"

Setup Checklist

1

WhatsApp Business Account

Create a WhatsApp Business account at business.whatsapp.com. Get your Phone Number ID from Meta Business Suite → WhatsApp → API Setup. Set the webhook URL to https://localflow-23-176418.polsia.app/api/webhook/whatsapp and verify token to localflow-demo-token.

2

OpenAI API Key

Get a key at platform.openai.com. Set OPENAI_API_KEY env var in Render dashboard. The AI uses GPT-4 to understand patient intent and generate natural responses.

3

Google Calendar (optional)

Create a Google Cloud project, enable Calendar API, create a service account, share your calendar with the service account email. Set GOOGLE_CALENDAR_ID and GOOGLE_SERVICE_ACCOUNT_KEY. Without this, demo uses realistic mock slots.

Demo Troubleshooting

!

WhatsApp webhook not receiving messages

Check: 1) Your webhook URL is publicly accessible, 2) Verify token matches, 3) Phone number is verified in Meta Business Suite, 4) The app is in "live" mode (not development/test).

!

AI responses are slow or failing

Check that OPENAI_API_KEY is set and has quota remaining. The API is called once per inbound message with a 5-second timeout. Falls back to a static response if API is down.

!

Show demo without real WhatsApp

Use /api/demo/dashboard — it shows the full workflow with mock chat bubbles. Use POST /api/demo/simulate-message with any phone/message to trigger the full AI flow and see results in the bookings panel. No WhatsApp credentials needed for demo mode.
