GoHighLevel API Integration

Overview

GoHighLevel provides a REST API that allows access to CRM data such as contacts, opportunities, conversations, and custom fields.

VINSI.AI integrates with GoHighLevel using OAuth 2.0, enabling secure, location-scoped access without exposing API keys to agents.

GoHighLevel authentication is handled via OAuth 2.0.

1. Navigate to Settings → API Integration → GoHighLevel
2. Click Connect with GoHighLevel API
3. Select the GoHighLevel location to authorize
4. Approve access to complete the connection

Access tokens are stored securely and refreshed automatically.
