RMS Cloud API
RMS Cloud is a cloud-native hospitality property management platform that runs front desk, reservations, channel distribution, revenue management, POS, payments, and guest experience for hotels, motels, campgrounds, RV parks, serviced apartments, and multi-property operators across 70+ countries. An API lets you programmatically pull reservations, guests, properties, rates, availability, and accounting records—and push bookings, rate updates, charges, and guest profiles back into RMS.
What is RMS Cloud?
RMS Cloud is a cloud-native property management platform that automates hospitality operations, enables direct bookings, and enhances guest experiences for accommodation providers across 70+ countries. Operators use RMS to run front desk and housekeeping, manage reservations and channel distribution, optimize revenue and rates, process payments through RMS Pay and point of sale, and surface performance through business intelligence dashboards.
Core product areas include:
- Property Management & Operations (front desk, housekeeping, maintenance, finance)
- Distribution, Revenue & Sales (reservations, channel manager, revenue management, booking engine, event management)
- Guest Experience (guest portal and personalization tools)
- Payments (RMS Pay and point-of-sale systems)
- Reporting & Analytics (hotel business intelligence and performance dashboards)
Common data entities:
- Reservations, Bookings, Stays, Availability, Holds
- Guests, Profiles, Companies, Travel Agents, Loyalty
- Properties, Areas/Rooms, Category Types, Inventory
- Rates, Rate Adjustments, Tariffs, Packages, Channels
- Accounts, Charges, Payments, Receipts, Transactions
The RMS Cloud Integration Challenge
Properties run mission-critical front-desk and distribution workflows on RMS daily, but turning a multi-property, multi-channel system into reliable API-driven automation is non-trivial:
- Token and key management: RMS exposes both long-lived API keys and short-lived access tokens, and integrations must rotate and refresh credentials without dropping live sessions
- Large surface area: with 530+ endpoints across reservations, rates, POS, accounting, and channels, mapping the right calls for a given workflow takes real domain knowledge
- Multi-property scoping: chains and parks operate many properties under one client, each with its own areas, category types, and rate tables that must be addressed correctly
- Two-way channel sync: availability, rates, and reservations flow in real time across OTAs and the booking engine, so writes must respect channel rules and avoid overbooking
- Rate and tariff complexity: seasonal tariffs, packages, derived rates, and adjustments make pricing reads and writes error-prone without normalization
- Payments and accounting integrity: charges, receipts, and RMS Pay transactions require careful idempotency and reconciliation against the guest ledger
How Supergood Creates RMS Cloud APIs
Supergood wraps RMS Cloud's authenticated REST surface and account workflows to deliver a resilient, normalized API layer for your RMS client and properties—so you integrate once and rely on consistent objects across reservations, rates, and accounting.
- Handles RMS API keys and short-lived access tokens with automated refresh and rotation
- Maintains session continuity and change detection as RMS releases and endpoint behavior evolve
- Normalizes responses across reservations, guests, properties, rates, and accounts so multi-property data stays consistent
- Respects channel rules, availability constraints, and rate scoping to keep writes safe across OTAs and the booking engine

API Endpoints
Authentication
/authenticateAuthenticate with an RMS API key or agent credentials and obtain a short-lived access token for downstream calls.
Reservations
/reservationsList reservations and stays across properties with filters for status, arrival/departure dates, channel, and guest.
Reservations
/create_reservationCreate a new booking against available inventory with rate, area/category, guest, and channel details.
Inventory
/availabilityRetrieve real-time availability and inventory by property, category type, and date range.
Rates
/ratesPull rate tables, tariffs, packages, and adjustments for pricing reads across properties and channels.
Guests
/guestsRetrieve guest profiles, companies, and travel agent records with contact and loyalty details.
Accounting
/post_chargePost a charge, payment, or receipt to a reservation account and reconcile against the guest ledger.
Use Cases
Sync reservations and availability across properties
- Pull reservations, stays, and holds from every property into a single warehouse - Stream arrival, departure, and cancellation events to downstream BI and CRM tools - Push real-time availability and inventory updates back to the booking engine and channels
Automate rate and channel distribution
- Read tariffs, packages, and derived rates and normalize them for pricing engines - Push rate and restriction updates across OTAs without portal clicks - Detect and resolve rate-parity gaps before they reach guests
Reconcile payments and guest accounting
- Sync charges, receipts, and RMS Pay transactions into general ledger and AR systems - Match POS activity to reservation accounts and the guest ledger - Surface outstanding balances and pending payments to finance workflows
Unify guest profiles and experience data
- Consolidate guest, company, and travel agent records across properties for a unified profile - Trigger personalization and loyalty workflows on check-in and checkout events - Push enriched guest data back into RMS for front-desk staff

Frequently asked questions
Yes. Supergood scopes calls to each property under your RMS client—addressing areas, category types, and rate tables correctly—so chains, parks, and multi-property portfolios share one consistent API surface.
Supergood manages both the long-lived API key and the short-lived access tokens RMS issues, refreshing and rotating credentials automatically so your integration never drops a live session.
Yes. Writes respect channel rules, availability constraints, and rate scoping, so rate and inventory updates flow to OTAs and the booking engine without overbooking or parity gaps.
Charges, receipts, and RMS Pay and POS transactions are exposed through the same normalized surface, with idempotency and reconciliation against the guest ledger built in.
Supergood continuously monitors RMS releases and endpoint behavior across the 530+ endpoint library and adapts the adapter automatically, so your integration keeps working as the platform changes.
