The Challenge
Slow manual replies to WhatsApp order and table reservation requests resulted in high customer drop-off rates and data transcription errors on spreadsheets.
Our Engineering Solution
Developed an automated WhatsApp Business API gateway using n8n and Supabase. The chatbot parses customer messages, questions, and audio clips using OpenAI Whisper/GPT, queries pricing and availability in Airtable, records bookings to Supabase, generates digital receipts, and syncs lead profiles to HubSpot CRM and Notion for staff kitchen-fulfillment tracking.
Key Implementation Details:
- Configured WhatsApp Business API Webhooks to listen for incoming messages. 2. Structured n8n flows utilizing OpenAI APIs for context analysis. 3. Linked Airtable databases for inventory/pricing and synced updates to HubSpot and Notion workspaces.
