Workflow Overview
This automation performs the following steps:
-
Trigger: A new lead arrives via the GHL Webhook.
-
Validation: OpenAI (GPT-4) checks lead quality and relevance.
-
AI Phone Call: VAPI.ai initiates an automated call to confirm appointment details.
-
Post-Call Analysis: OpenAI interprets the call result (booking_made=YES/NO).
Conditional Actions:
If YES: Updates GoHighLevel CRM and sends confirmation emails to the client and owner.
If NO: Alerts the owner via email about the failed booking.
Prerequisites
Active accounts and API keys for:
- GoHighLevel (webhook setup)
- VAPI.ai (phone call API)
- OpenAI (GPT-4 access)
- Email service (e.g., SMTP, SendGrid, or Gmail)
How to Use This Template
Step 1: Import the Template
Import the JSON into your self-hosted n8n instance (requires Community Nodes like @n8n/n8n-nodes-langchain).
Step 2: Configure Credentials
GHL Webhook: Replace YOUR_WEBHOOK_ID with your GoHighLevel webhook ID.
OpenAI Nodes: Add your OpenAI API key (replace placeholder BxLbA94QZt0ifZsC).
VAPI Call Node: Ensure the VAPI.ai endpoint (https://api.vapi.ai/call/phone) has valid API credentials.
Email Nodes: Configure SMTP or API credentials for your email service.
Step 3: Enable Disabled Nodes
Activate the Post-call Analysis node if needed (disabled by default).
Finding Your GHL Webhook ID In GoHighLevel, navigate to Automations → Webhooks.
Create a new webhook and copy its unique ID into the GHL Webhook node.
Initial Test Run
Simulate a Lead: Manually trigger the GHL webhook with test lead data.
Debugging:
Verify OpenAI validates the lead.
Check if VAPI.ai initiates a call (use a test phone number).
Confirm CRM updates and emails are sent conditionally.
Production Prep:
Enable error-handling loops for failed calls.
Adjust GPT-4 prompts for stricter validation.
