AI Customer Support Chatbot Automation

I need an AI-driven customer-support workflow that lives on my website chat widget and in our support email inbox, answering questions around the clock without human intervention. The vision is simple: a single n8n pipeline that catches incoming messages, feeds them through the ChatGPT API, and fires back an accurate, conversational reply drawn from a living FAQ stored in Google Sheets.

The same flow must confidently tackle both day-to-day queries (order status, returns, shipping) and the long-tail, case-specific questions that only pop up once in a while. Whenever an answer cannot be produced with high certainty, the bot should gracefully escalate the thread to a human agent while tagging the case for future training.

Core workflow
• Webhooks (or native nodes) in n8n capture new website-chat events and incoming email.
• The message, relevant metadata, and customer context are passed to OpenAI (ChatGPT API).
• The model consults a Google Sheet of curated Q&A pairs, blends that knowledge with the user prompt, and generates an instant reply.
• A response is delivered back to the original channel in real time, and the entire exchange is logged to the same sheet for analytics and continuous improvement.

Acceptance criteria
1. Real-time replies under five seconds for both website chat and email.
2. Minimum 70 % reduction in tickets routed to human staff during a three-day pilot.
3. Fully documented n8n workflow (export JSON), environment variables, and setup guide so the system can be cloned or scaled at will.
4. Clear hand-off logic that flags low-confidence answers and emails the support team automatically.

If you know your way around n8n, ChatGPT, webhooks, and Google Sheets integrations, this build should be straightforward. Once the foundation is in place I’ll handle future channel expansions (social media, SMS, etc.) using the same pattern.
