Step-by-Step Guide: Setting Up a No-Code WhatsApp Chatbot with Ragdoll AI and N8N

Learn how to build a no-code AI WhatsApp agent powered by RAG, using Ragdoll AI and N8N.

Requirements‍

Before setting up the N8N workflow, ensure you have the following:

• A Ragdoll AI knowledge base, with your desired data uploaded or connected.
• A Meta WhatsApp app set up with the necessary credentials.
• An N8N account.

How It Works

1. A WhatsApp trigger captures incoming messages from customers, filtering out non-text messages.
2. The customer's message is sent to the AI Agent, which queries the Ragdoll AI knowledge base.
3. The Agent's response is sent back to the user via the WhatsApp node.

How to Use

1. Clone this workflow by downloading the JSON files. Copy the JSON code and paste it onto the N8N canvas, then add the required credentials.
2. Click the "Test Workflow" button to start listening for incoming WhatsApp messages.
3. Send a message to your designated WhatsApp number, and you should receive a response from the AI sales agent.

Troubleshooting and Customization

• If you are self-hosting N8N, ensure you set up the "webhook_url" environment variable; otherwise, your workflow may not function correctly.
• You can tweak the system prompt within the AI Agent node to adjust its desired tone, add specific company guidelines, or ask for specific format in its outputs.
