It transforms manual booking conversations into a seamless self-service experience directly within WhatsApp.\n\n##### Who is this for?\n\nService businesses wanting WhatsApp-based appointment booking\nConsultants and agencies offering scheduled calls or consultations\nTeams using Airtable for CRM and Google Calendar for scheduling\nBusinesses looking to reduce booking friction with conversational commerce\n\n##### What problem does this workflow solve?\n\nAppointment booking typically involves back-and-forth messaging to find available times, collect customer details, and confirm bookings. This workflow eliminates that friction by providing an interactive booking flow within WhatsApp that checks real-time calendar availability, collects customer information, and automatically syncs bookings to your CRM and calendar.\n\n##### How it works\n\n**Webhook Entry Point:** A single webhook handles both GET (Meta verification) and POST (messages/flows) requests - required due to Meta's single-webhook-per-app restriction.\n\n**Message Routing:** Incoming requests are classified as either regular WhatsApp messages or encrypted Flow requests, then routed accordingly.\n\n**WhatsApp Flow Handling:** Flow requests are decrypted using RSA/AES-GCM encryption. The workflow handles multiple Flow actions:\n- INIT: Returns consultation types and date constraints\n- SERVICE_SELECTION: Processes service and customer details\n- DATE_TIME_SELECTION: Queries calendar availability for selected date\n- CONFIRMATION: Displays booking summary\n- COMPLETE_BOOKING: Finalizes the booking\n\n**AI Agent:** For regular text messages, an OpenAI-powered agent classifies user intent. When booking intent is detected, it triggers the consultation template with the WhatsApp Flow.\n\n**Booking Process:** On completion, the workflow:\n1. Creates or updates customer in Airtable\n2. Creates booking record with event details\n3. Creates Google Calendar event\n4. Sends WhatsApp confirmation message\n\n##### Good to Know\n\n**Verify Token:** The `WHATSAPP_VERIFY_TOKEN` environment variable is required for Meta webhook verification. Set this to any secure string and use the same value in Meta Developer Portal.\n\n**Cloud vs Self-hosted:** Cloud n8n instances are easier to configure as they have public URLs. Self-hosted instances require additional setup for public accessibility.\n\n**Hostinger/Docker Setup:** For self-hosted instances, configure public webhook access in your `docker-compose.yml` or reverse proxy configuration.\n\n**Meta Prerequisites:** You'll need:\n- Facebook Account\n- Meta Developer App\n- WhatsApp Business Account (linked to Developer App)\n- WhatsApp Business Phone Number\n\n**Health Checks:** Meta sends periodic ping requests to verify webhook availability. The workflow handles these automatically with a 200 response.\n\n**Single Webhook Restriction:** Meta only allows one webhook URL per WhatsApp app, which is why all message types flow through a single endpoint with routing logic.\n\n**Encryption:** WhatsApp Flows use end-to-end encryption. The workflow handles RSA decryption (for AES key exchange) and AES-128-GCM encryption/decryption for Flow data.\n\n##### Requirements\n\n- Meta Business Account with WhatsApp Business API access\n- WhatsApp Business App in Meta Developer Portal\n- n8n instance (cloud or self-hosted with public URL)\n- OpenAI API key (for intent classification with GPT-4o)\n- Airtable account with base containing: Customers, Services, Bookings tables\n- Google Calendar with OAuth credentials\n\n##### Environment Variables\n\n| Variable | Description |\n|----------|-------------|\n| `WHATSAPP_VERIFY_TOKEN` | Webhook verification token (match in Meta Developer Portal) |\n| `WHATSAPP_PRIVATE_KEY` | RSA private key for Flow encryption (PEM format) |\n| `WHATSAPP_PRIVATE_KEY_PASSPHRASE` | Passphrase for the RSA private key |\n| `GOOGLE_CALENDAR_ID` | Calendar ID for availability checks and event creation |\n\n##### Setup\n\n1. **Meta Business Setup**\n - Create a Meta Developer App at developers.facebook.com\n - Add WhatsApp product to your app\n - Set up a WhatsApp Business Account\n - Generate a permanent access token\n\n2. **Import Workflow**\n - Import `personal-booking-whatsapp-flow.json` into n8n\n - Replace placeholder credential IDs with your actual credentials\n\n3. **Configure Credentials**\n - WhatsApp: HTTP Bearer Auth with your access token\n - OpenAI: API key for GPT-4o\n - Airtable: OAuth2 authentication\n - Google Calendar: OAuth2 authentication\n\n4. **Set Environment Variables**\n - Configure all variables listed above in n8n settings\n\n5. **Configure Webhook in Meta**\n - Navigate to WhatsApp > Configuration in Developer Portal\n - Set webhook URL to your n8n webhook endpoint\n - Enter your verify token\n - Subscribe to messages webhook field\n\n6. **Create WhatsApp Flow**\n - In WhatsApp Manager, create a new Flow\n - Use the JSON from `whatsapp-flow.json` as your Flow definition\n - Publish the Flow and note the Flow ID\n\n7. **Create Message Template**\n - Create a template with a Flow button component\n - Link it to your published Flow\n - Submit for approval\n\n##### Airtable Schema\n\n**Customers Table:**\n- `customer_name` (text)\n- `customer_email` (email)\n- `phone_number` (text)\n- `created_at` (date)\n\n**Services Table:**\n- `service_name` (text)\n- `service_key` (text) - e.g., \"30_min\", \"60_min\"\n- `duration_minutes` (number)\n\n**Bookings Table:**\n- `customer_email` (text)\n- `service_type` (linked to Services)\n- `event_date` (date)\n- `event_time` (text)\n- `booking_status` (select: Pending, Confirmed, Cancelled)\n- `calendar_event_id` (text)\n- `created_at` (date)\n\n##### Customizing this workflow\n\n**Consultation Types:** Modify the INIT handler code node to add/change consultation options and durations.\n\n**Business Hours:** Adjust the calendar availability logic in the date refresh handler to match your working hours.\n\n**AI Agent Prompts:** Customize the system prompt in the AI Agent node to match your business context and available services.\n\n**Messaging Templates:** Create additional WhatsApp templates for different services (quotes, information requests) and add corresponding tools to the AI agent.\n\n**CRM Fields:** Extend the Airtable schema and update the booking creation nodes to capture additional customer data.\n\nMade by
