Square Integration

FairEngineAPI integrates directly with Square’s Booking, Transaction, and Catalog APIs, allowing businesses to handle payments, appointments, and availability in real time. Square provides the financial and scheduling backbone, while FairEngine customizes and extends that functionality for each unique business.

FairEngineAPI: The Engine Behind the Integration

While Square provides the foundation for scheduling and transactions, FairEngineAPI is what makes everything truly work for your business. It acts as the connective layer that bridges your complex booking logic with Square’s ecosystem—handling the unique rules, workflows, and pricing structures that standard booking tools can’t.
FairEngineAPI interprets your business’s individual logic—like availability constraints, multi-service bookings, seasonal rates, and private charter rules—and syncs that intelligence directly into Square. This ensures every booking, payment, and schedule update stays accurate, consistent, and aligned with how your business actually operates.
In short, Square powers your operations, but FairEngineAPI makes it yours—transforming a generic system into a tailored, automated solution designed for your exact needs.
