Create an Automated Customer Support Assistant with GPT-4o and GoHighLevel SMS

📌 AI Agent via GoHighLevel SMS with Website-Based Knowledgebase

This n8n workflow enables an AI agent to interact with users through GoHighLevel SMS, leveraging a knowledgebase dynamically built by scraping the company's website.

❓ Problem It Solves

Traditional customer support systems often require manual data entry and lack real-time updates from the company's website. This workflow automates the process by:

Scraping the company's website at set intervals to update the knowledgebase. Integrating with GoHighLevel SMS to provide users with timely and accurate information. Utilizing AI to interpret user queries and fetch relevant information from the updated knowledgebase.

🧰 Pre-requisites

Before deploying this workflow, ensure you have:

An active n8n instance (self-hosted or cloud). A valid OpenAI API key (or any compatible AI model). A Bright Data account with Web Unlocker setup. A GoHighLevel SMS LeadConnector account. A GoHighLevel Marketplace App configured with the necessary scopes. Installed n8n-nodes-brightdata community node for Bright Data integration (if self-hosted).

⚙️ Setup Instructions

1. Install the Bright Data Community Node in n8n

For self-hosted n8n instances:

Navigate to Settings → Community Nodes. Click on Install. In the search bar, enter n8n-nodes-brightdata. Select the node from the list and click Install.

2. Configure Bright Data Credentials

Obtain your API key from Bright Data. In n8n, go to Credentials → New, select HTTP Request. Set authentication to Header Auth. In Name, enter Authorization. In Value, enter Bearer <your_api_key_from_Bright_Data>. Save the credentials.

3. Configure OpenAI Credentials

Add your OpenAI API key to the relevant nodes. If you want to use a different model, replace all OpenAI nodes accordingly.

4. Set Up GoHighLevel Integration

a. Create a GoHighLevel Marketplace App

Go to https://marketplace.gohighlevel.com Click My Apps → Create App Set Distribution Type to Sub-Account Add the following scopes: locations.readonly contacts.readonly contacts.write opportunities.readonly opportunities.write users.readonly conversations/message.readonly conversations/message.write Add your n8n OAuth Redirect URL as a redirect URI in the app settings. Save and copy the Client ID and Client Secret.

b. Configure GoHighLevel Credentials in n8n
