System: "You are an AI assistant for [Agency Name].
Your goal: qualify leads and book discovery calls.
Rules:

Setting Up GHL Webhooks for Automation
To connect GoHighLevel with n8n or Make.com, you need to configure webhook triggers in GHL. Here’s the process:
- Go to Settings → Integrations → Webhooks in your GHL sub-account
- Click Add New Webhook
- Paste your n8n webhook URL (e.g.,
https://your-n8n.com/webhook/ghl-leads) - Select triggers: Contact Created, Opportunity Status Changed, SMS Received, etc.
- Enable the webhook and test with a dummy lead submission
- In n8n, use the Webhook node to receive and process the data
