n8n AI Customer Support
Chatbot

An intelligent n8n automation that handles incoming customer support tickets end-to-end — powered by Groq AI (100% free). When a customer submits a ticket, the workflow automatically classifies the issue, looks up the knowledge base, generates a personalized AI response, logs everything to Google Sheets, sends the reply via email, notifies the team on Slack, and escalates complaints immediately.

How it works

Ingest
Webhook ticket receipt

A webhook node receives the incoming customer ticket from any source — form, email, or chat — and immediately responds to acknowledge receipt.

Classify
AI category detection

Groq AI reads the ticket message and classifies it into one of six categories: Billing, Technical, Shipping, Refunds, Complaint, or General.

Lookup
Knowledge base search

The workflow queries an internal KB to find the most relevant answer or policy doc before composing a response.

Route
Smart branch routing

A Switch node sends each ticket down the correct branch based on its AI-detected category — complaints get escalated instantly.

Respond
Personalized AI reply

Each branch runs its own AI node (powered by Groq) to craft a context-aware, empathetic response using the KB answer and customer details.

Deliver
Log, email & notify

Appends the ticket to Google Sheets, sends the AI response to the customer via email, and pings the team on Slack. Complaints trigger an instant escalation message.
