AI WhatsApp Restaurant Reservations with Google Sheets

This n8n workflow streamlines restaurant reservations by handling incoming WhatsApp messages with AI-powered parsing. It extracts guest details like name, date, time, and party size from free-form texts, validates requests, checks real-time availability in Google Sheets (or Airtable/MySQL), calculates group discounts, and generates personalized confirmations using OpenAI. Optional automated reminders ensure no-shows are minimized, all without manual intervention.

Key benefits include significant time savings for staff, improved customer experience through natural, conversational responses, and scalability for high-volume bookings. The modular design allows easy swaps for different triggers, databases, or messaging platforms, making it adaptable for hotels, events, or clinics. AI integration reduces errors in intent detection and enables upsells like menu suggestions or alternate slots.

The workflow triggers on WhatsApp Business Cloud API messages, processes via AI Function for extraction, lookups data, computes logic, composes replies with OpenAI, sends responses, and schedules follow-ups. Ideal for small to medium restaurants seeking CRM automation in sales and lead nurturing.

Use cases: Busy eateries managing peak-hour bookings, multi-location chains syncing reservations, or pop-up events needing quick setup. Customize with media attachments, localization, or advanced AI prompts for enhanced engagement.
