Tutorial how to integrate n8n with Live Helper Chat

This tutorial demonstrates how to integrate n8n workflow automation with Live Helper Chat to create an AI-powered chatbot using OpenAI.

For a visual walkthrough of this integration process, you can watch our tutorial video on YouTube.

Prerequisites​

Before starting, you'll need:

  • n8n instance (locally hosted or SaaS version from https://n8n.io/)
  • Live Helper Chat installation with admin access
  • OpenAI API key (for the AI assistant functionality)

Overview​

In this integration example, we'll:

  1. Set up n8n to handle chat workflows
  2. Configure a Rest API connection between Live Helper Chat and n8n
  3. Create a bot that uses OpenAI as an assistant
  4. Connect everything together for automated responses

This tutorial provides a foundation that you can extend with your own custom workflows and integrations.

n8n Configuration​

You can download the pre-configured n8n workflow file and import it directly into your n8n instance.

Important: Configure OpenAI Credentials​

Before using the workflow, you must configure your OpenAI API credentials in n8n:

  1. Open the imported workflow in your n8n instance
  2. Locate the OpenAI node in the workflow
  3. Click on the OpenAI node to open its configuration
  4. Enter your OpenAI API key in the credentials field
  5. Save the workflow

Without proper OpenAI credentials, the AI assistant functionality will not work.

Option 1: Local n8n hosting with Docker Compose​

For local development, you can use the following docker-compose.yml file to quickly set up n8n with Redis:

  1. Create a new directory for your n8n setup
  2. Save the content below as docker-compose.yml
  3. Run docker-compose up -d in the same directory
version: '3.8'

services:
  redis:
    image: redis:7-alpine
    container_name: n8n_redis
    restart: unless-stopped
    volumes:
      - redis_data:/data
    networks:
      - n8n_network

  n8n:
    image: docker.n8n.io/n8nio/n8n
    container_name: n8n
    restart: unless-stopped
    ports:
      - "5678:5678"
    environment:
      - GENERIC_TIMEZONE=Europe/Vilnius
      - TZ=Europe/Vilnius
      - DB_TYPE=redisdb
      - DB_REDIS_HOST=redis
      - DB_REDIS_PORT=6379
      - DB_REDIS_DB=0
    volumes:
      - n8n_data:/home/node/.n8n
    depends_on:
      - redis
    networks:
      - n8n_network

volumes:
  n8n_data:
  redis_data:

networks:
  n8n_network:
    driver: bridge

Option 2: Using n8n SaaS​

If you prefer to use n8n's hosted service:

  1. Sign up at n8n.io
  2. Create a new workflow
  3. Import the workflow file

Live Helper Chat Configuration​

Step 1: Import Rest API Configuration​

  1. Download the Rest API configuration
  2. In Live Helper Chat admin panel, go to System → Rest API
  3. Click Import and select the downloaded file
  4. Configure the API endpoint to point to your n8n instance. Enter correct Host and Sub URL

Step 2: Import Bot Configuration​

  1. Download the bot configuration
  2. In Live Helper Chat admin panel, go to Chats → Bots
  3. Click Import and select the downloaded file
  4. During import, choose the Rest API configuration you imported in Step 1

Configuration Details​

Step 3: Activate Bot in Department​

After completing the configuration steps above:

  1. Navigate to System → Departments in the Live Helper Chat admin panel
  2. Select the department where you want to enable the n8n bot
  3. In the department settings, locate the Bot section
  4. From the bot dropdown menu, select your newly imported n8n bot
  5. Save the department configuration

The bot will now be active for incoming chats in the selected department.

n8n Workflow Setup​

The imported n8n workflow includes:

  • Webhook trigger to receive messages from Live Helper Chat
  • OpenAI integration for AI responses
  • Response formatting for Live Helper Chat compatibility

Testing the Integration​

  1. Start a chat on your Live Helper Chat installation
  2. Send a message to trigger the bot
  3. Verify that the message is processed by n8n and returns an AI-generated response

Other use cases​

There are a few YouTube videos which can help integrate n8n with various third party services and proxy them to Live Helper Chat
