Little Hotelier API
Little Hotelier is an all-in-one platform from SiteMinder built for small properties—hotels, B&Bs, guesthouses, motels, and vacation rentals—combining a front-desk property management system, channel manager across 400+ booking channels, direct booking engine, payments, and a website builder. An unofficial API lets you programmatically pull reservations, guests, rooms, rates, and availability—and push updates like new bookings, room assignments, rate and inventory changes, and invoices back into Little Hotelier.
What is Little Hotelier?
Little Hotelier is an all-in-one accommodation management platform from SiteMinder, purpose-built for small properties such as hotels, bed & breakfasts, guesthouses, motels, resorts, lodges, vacation rentals, inns, and campsites.

Operators use Little Hotelier to manage the front desk, reservations, and guests; distribute availability across hundreds of booking channels; take direct bookings; and process payments from one connected platform.

- Direct Booking Engine and metasearch integration (Google Hotel Ads, Trivago, TripAdvisor)
- Payments processing across channels and direct bookings

- Revenue tools including Dynamic Revenue Plus pricing recommendations and Channels Plus
Common data entities:

- Channels, Connections, Mappings
- Payments, Invoices, Transactions
The Little Hotelier Integration Challenge
Small operators run their entire business on Little Hotelier, but turning its portal- and channel-driven workflows into API-driven automation is non-trivial:
- Partner-gated APIs: Programmatic access flows through SiteMinder's developer programs (SiteConnect, pmsXchange, Channels Plus), which require partnership agreements and certification before access
- Limited ARI access: Availability, Rates, and Inventory data is not readily exposed from the Little Hotelier and SiteMinder channel manager surface for general integrators
- Mobile-first, web-portal workflows: Much day-to-day data lives behind the calendar UI and mobile app rather than a documented public REST surface
- Channel mapping complexity: Reservations arrive normalized from 400+ channels, each with its own rate-plan and room-type mappings to reconcile
- Hotel-code and account scoping: Integrations are scoped per property hotel code, and small operators rarely have engineering resources to wire them up
- Real-time sync expectations: Availability and rate pushes must propagate to channels promptly to avoid overbookings and rate parity issues
How Supergood Creates Little Hotelier APIs
Supergood reverse-engineers Little Hotelier's authenticated browser and mobile flows to deliver a resilient API layer for your property—so you can read and write reservations, guests, rooms, rates, and availability without waiting on partner-API certification.
- Handles username/password and MFA securely within a managed session
- Maintains session continuity with automated refresh and change detection
- Normalizes responses across reservations, guests, rooms, rates, and availability so you integrate once and rely on consistent objects
- Reconciles channel-specific room-type and rate-plan mappings into a unified schema scoped to your property hotel code
