Multi-Platform E-Commerce Chatbot with AI Routing and Knowledge Retrieval

This advanced n8n workflow enables an AI-powered customer support chatbot for both Shopify and WooCommerce platforms, integrated with GPT-4o, Gemini, and retrieval-augmented generation (RAG) techniques. The workflow starts with a webhook trigger that activates whenever a chat message is received from a user. The message undergoes initial routing via an AI model to identify if the query pertains to Shopify, WooCommerce, or is a general knowledge question.

Based on this classification, the workflow routes the conversation to the appropriate AI-powered agent—either Shopify or WooCommerce—or handles general queries using a retrieval system. For e-commerce questions, it fetches product or order data using Shopify or WooCommerce tools, employing GraphQL or REST APIs to gather precise information.

For general questions, the workflow utilizes Pinecone and AWS Bedrock to retrieve relevant knowledge chunks, which are then used by GPT-4o-mini to generate accurate and helpful responses.

The workflow also maintains conversation context with memory nodes, ensuring coherent multi-turn interactions across sessions. It consolidates final responses from the relevant agent and outputs it to the user.

This setup is ideal for retailers operating multiple e-commerce platforms who wish to provide instant, intelligent customer support, order inquiries, or product information via chat, enhancing customer engagement while reducing operational overhead.
