Zenoti API
Zenoti is an all-in-one cloud business-management platform for salons, spas, med spas, and fitness studios—covering online booking, point of sale, payments, memberships, gift cards, marketing, inventory, payroll, and med-spa charting. An unofficial API lets you pull guests, appointments, invoices, payments, memberships, packages, gift cards, inventory, and employee data—and push updates like new bookings, reschedules, and membership changes back into Zenoti.
What is Zenoti?
Zenoti is an all-in-one, cloud business-management platform for the beauty, wellness, and fitness industries—salons, spas, med spas, barbershops, and fitness studios. Operators run the full guest lifecycle on Zenoti: online booking and appointment scheduling, point of sale and payments, memberships and packages, gift cards and loyalty, marketing, inventory, payroll and tipping, and clinical forms and charting for med-spa services. The platform serves 30,000+ businesses across 50+ countries, including TONI&GUY, European Wax Center, Hand & Stone, and Skin Laundry.
Core product modules include:
- Online Booking and Appointment Book (scheduling across providers, rooms, and centers)
- Kiosk & Point of Sale, Payments, and Integrated Payroll & Tipping
- Memberships & Packages, Gift Cards & Referrals, and Loyalty Programs
- Inventory Management and Employee Performance Management (plus the MyZen provider app)
- Forms & Charting / SOAP notes for med-spa and medical-aesthetic services
- Marketing, Dynamic Pricing, Automated Upsells, Waitlist Management, and Abandoned Cart Recovery
Common data entities:
- Guests, guest profiles, appointment history, and reviews
- Appointments, services, providers, rooms, and center schedules
- Invoices, payments, tips, and gift-card balances
- Memberships, packages, and loyalty point balances
- Inventory, products, and stock levels
- Employees, schedules, performance, and payroll/tipping records
- Forms, charting, and SOAP/treatment notes (med-spa)
The Zenoti Integration Challenge
Zenoti is the system of record for a beauty or wellness business's daily operations, but turning that into clean, API-driven automation is non-trivial:
- Customer-gated API access: production API keys are generated from inside the Zenoti backend app by an existing customer—there is no public self-serve developer signup
- No official SDKs: integrations are built directly against raw REST endpoints, with authentication and pagination handled by hand
- Broad, multi-module surface: 200+ endpoints span Appointments, Guests, Invoices, Memberships, Packages, Gift Cards, Classes, Inventory, and Employees, each with its own object model
- Per-organization rate limits: an org-wide request cap (around 60 calls/minute) forces careful batching and backoff across centers
- Polling over events: webhooks exist for some events but coverage is uneven, so many workflows require scheduled polling and change detection
- Multi-center variance: chains run many centers with their own catalogs, providers, and pricing, so a single query shape must adapt per location
How Supergood Creates Zenoti APIs
Supergood reverse-engineers Zenoti's authenticated sessions and documented REST surface to deliver a resilient, normalized API for your Zenoti organization—across every center and module.
- Manages API-key and session authentication securely, including token refresh and org-wide rate-limit handling
- Normalizes responses across Appointments, Guests, Invoices, Memberships, and Inventory so you integrate once and rely on consistent objects
- Bridges webhook gaps with scheduled polling and change detection for events Zenoti doesn't push
- Adapts to multi-center catalogs, providers, and pricing so per-location differences don't break your integration

Automate booking and waitlist workflows
- Create, reschedule, and cancel appointments programmatically against provider and room availability - Push waitlist and abandoned-cart events into outbound messaging - Surface open slots to a custom booking site or partner channel
Reconcile POS, payments, and gift cards
- Sync invoices, payments, and tips into accounting and general-ledger systems - Track gift-card issuance and redemption balances across centers - Export end-of-day sales for finance and analytics
Keep membership and inventory data in sync
- Pull membership and package holdings, redemptions, and balances for reporting - Monitor inventory and stock levels across centers for replenishment - Trigger renewal and retention workflows when memberships lapse

Frequently asked questions
Yes. Supergood works against your own authenticated Zenoti organization and the API key generated from your Zenoti backend app—there is no separate public developer signup required.
Yes. Supergood normalizes data across every center in your organization, so guests, appointments, invoices, and inventory are exposed through one consistent surface regardless of location.
Supergood applies adaptive throttling and backoff tuned to Zenoti's org-wide request cap (around 60 calls per minute), so high-volume syncs stay within platform limits without manual tuning.
Yes. Where Zenoti's webhook coverage is incomplete, Supergood backfills with scheduled polling and change detection so you still receive timely booking, payment, and membership events.
Forms, charting, and SOAP/treatment notes are exposed through the same normalized API surface where your Zenoti configuration captures them, alongside guest and appointment entities.
