4. Sync Revenue and Financial Metrics

Pull and push revenue, transactions, upsells, promo use, and any KPI data needed for dashboards and automation.

5. Sync Tee Times and Bookings

Sync all bookings, cancellations, reschedules, confirmations, and attendance between the booking engine and HighLevel in real time.

6. Sync Forms and Lead Activity

Pull form submissions, create or update contacts, and map fields and tags into the correct sub-account.

Assign data to the right franchise sub-account, keep data separated, and support proper versioning for a Marketplace app.
