Automate WhatsApp Orders with GPT-4o & Google Sheets

Unlock seamless communication and operational efficiency for your business with our robust n8n workflow. Automate your WhatsApp orders by integrating the power of OpenAI's GPT-4o with Google Sheets to transform your message management, order processing, and support escalation. This workflow builds an AI-driven assistant that smartly classifies and routes messages, ensuring every customer request is handled swiftly and accurately.

What this workflow does

• Upon receiving a new WhatsApp message, the workflow triggers to capture the sender's phone number, message content, and timestamp.
• Utilizes OpenAI (GPT-4o) to categorize the message intent as FAQ, ORDER, TRACK_ORDER, or HUMAN_SUPPORT.
• Handles FAQ requests by retrieving context from a Pinecone vector index, generates precise responses with OpenAI, and communicates replies back via WhatsApp.
• Processes ORDER requests by extracting order details, validating the availability against a Google Sheets product catalog, updating orders and inventory if possible, and sending confirmation messages.
• Facilitates TRACK_ORDER queries by extracting order IDs and updating customers with current status fetched from Google Sheets.
• Escalates HUMAN_SUPPORT requests by logging details to a Slack channel and acknowledging receipt through WhatsApp.
