Frequently asked questions
RMS Cloud scores D+ on the API Report Card. RMS Cloud publishes a 530+ endpoint REST API with open Swagger and Postman docs spanning reservations, rates, guests, folios, housekeeping, and POS. Production credentials require a partner application and certification, even for in-house teams, and rate limits are scoped per partner.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly.
RMS Cloud (legal entity: RMS, The Hospitality Cloud, parent RMS Aust Pty Ltd, HQ Keilor Park, Victoria, Australia, founded 1983, cloud product launched in the mid-2000s) is an end-to-end cloud-native property management platform purpose-built for multi-property hospitality operators.
POS / Hospitality, uniquely broad within the vertical because RMS deliberately serves both indoor and outdoor accommodation. A 4-property holiday-park group with 1,200 powered sites, 80 cabins, two marinas and three on-site cafés runs RMS Cloud as the single tenant for all operations.
RMS Cloud is a clear category leader within outdoor hospitality (holiday parks / campgrounds / RV parks / marinas) globally, and a credible top-10 cloud PMS within the broader independent-hotel and multi-property accommodation segment, but not a top-tier brand name outside hospitality circles.
For an accommodation operator running their front desk, channel manager, payments, POS, guest portal, housekeeping and BI on RMS Cloud, the platform is the de-facto operational system of record.
Founded in 1983 in Melbourne, Australia, originally as a desktop reservations system for Australian caravan parks and motels; pivoted to a cloud-native, multi-tenant SaaS platform in the mid-2000s and has been continuously expanding since.
Production API access is gated behind a partner-application and certification process, independent developers and customer in-house teams cannot self-serve production credentials. Rate limits, throttling thresholds, retry semantics and webhook delivery guarantees are sparsely documented in the public specification, integrators learn ceilings empirically. Full sourced list under Sources below.
Common alternatives include Newbook (Storable), Campspot, ResNexus, CampLife, Roverpass, Cloudbeds. Graded alternatives appear under "More from the report card" below.
Grades measure one thing: can a customer's engineering team get their own data out programmatically? We check six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and roll them into a letter grade. Grades get re-verified, and they only move on evidence.
Yes. Supergood maintains an unofficial RMS Cloud API and MCP server so AI agents and internal tools can read and write RMS Cloud data. See the RMS Cloud integration docs at supergood.ai/docs/rms-cloud-api.
