• Pull and push revenue, transactions, upsells, promo use, and any KPI data needed for dashboards and automation.
• Sync Tee Times and Bookings
• Sync all bookings, cancellations, reschedules, confirmations, and attendance between the booking engine and HighLevel in real time.
• Sync Forms and Lead Activity
• Pull form submissions, create or update contacts, and map fields and tags into the correct sub-account.
• Support a Multi Location Franchise Model
