### Use Case: Custom Lead Scoring System

**Problem:** A B2B sales agency needed more advanced scoring than GHL provided.

**Solution:**

- API checks contact history daily
- Applies weighted scores based on email opens, form fills, and replies
- Updates a custom field in GHL
- Triggers automation if score crosses a threshold

This setup gave the client actionable insights without logging in.
