Complete business WhatsApp AI-Powered RAG Chatbot using OpenAI

n8n template #2845

Summary

Use template
The provided workflow in n8n is designed to create a Business WhatsApp AI RAG (Retrieval-Augmented Generation) Chatbot. How it works: Webhook Setup: The workflow begins by setting up webhooks for verification and response. The Verify webhook receives GET requests and sends back a verification code, while the Respond webhook handles incoming POST requests from Meta regarding WhatsApp messages. Message Handling: Once a message is received, the workflow checks if the incoming JSON contains a user message. If it does, the message is processed further; otherwise, a generic response is sent. AI Agent Interaction: The user's message is passed to the AI Agent node, which uses a conversational agent

How to set it up

  1. Open template #2845 on n8n.io and click Use for free, or copy the template JSON and paste it onto an empty canvas in n8n.
  2. Create 5 credentials under Credentials → Add credential: Google Drive, WhatsApp Business Cloud, Embeddings OpenAI, OpenAI Chat Model, Qdrant Vector Store. Then open each of those nodes and pick the credential.
  3. Check the model in the AI Agent node. The template may point at a model your account can't use; swap it for one you have access to.
  4. Click Execute workflow and step through each node's output to confirm the data looks right.
  5. Toggle the workflow to Active so its trigger runs on its own.
