Automating WhatsApp replies with AI can save hours of manual work for businesses. In this tutorial, we’ll build a WhatsApp RAG (Retrieval Augmented Generation) AI Agent using n8n and WhatsApp Business Cloud API.
This agent will:
- ✅ Read incoming WhatsApp messages
- ✅ Use RAG (Retrieval Augmented Generation) for smarter, context-based replies
- ✅ Connect to your own knowledge base (Google Sheets, product data, FAQs, etc.)
- ✅ Send automated responses directly on WhatsApp Business Cloud API
- ✅ Save you hours by automating customer support & business communication
Best of all, you can download the workflow JSON file to get started instantly.
