How to Connect a Custom Website to GoHighLevel Calendar

A custom website can connect to GoHighLevel to use GHL calendars without embedding the standard widget.

Connection Architecture

Website → Backend API → GoHighLevel API → GHL Calendar

The website never directly accesses GHL. Your backend handles authentication.

What You Need

1. GoHighLevel account with API access
2. Backend server (Node.js, etc.)
3. Custom frontend (React, Next.js, etc.)

Backend Endpoints

Create endpoints for:

• GET /api/availability - fetch available slots

• POST /api/booking - create appointment

• PUT /api/booking/:id - reschedule

• DELETE /api/booking/:id - cancel

Frontend Integration

Your React components:

1. Fetch availability when user selects a date.
2. Display slots as clickable buttons.
3. Collect contact information.
4. Submit booking to your backend.
5. Show confirmation.

Security

• Keep GHL credentials server-side only.

• Validate all input.

• Rate limit requests.

• Handle errors gracefully.

Benefits

• Complete design control

• Custom qualification

• Calendar routing

• AI booking support

• Better analytics
