SiteMinder is an Australian hotel commerce platform (ASX SDR) that connects hotels with more than 450 online distribution channels, including OTAs (Booking.com, Expedia, Airbnb, Agoda), metasearch sites (Google, Trivago, TripAdvisor), and global distribution systems. Through its developer portal at developer.siteminder.com, SiteMinder publishes five integration APIs spanning property management system connectivity (pmsXchange), booking channel distribution (SiteConnect, Channels Plus), metasearch publication (SMX), and direct booking flows (Direct Booking API). The platform serves more than 53,000 properties across 150 countries and manages over three million hotel rooms.
SiteMinder is listed with 5 APIs on the APIs.io network. Tagged areas include Hospitality, Hotel Distribution, Channel Manager, Booking Engine, and Travel.
SiteMinder’s developer surface includes developer portal, getting-started guide, signup flow, pricing, support, FAQ, engineering blog, and 10 more developer resources.
Regulatory Posture applies to this provider. Its tags matched the
Horizontal (data, software, accessibility, platform) regime, so
Regulatory Posture carries 15 points of the composite.
If this regime is wrong for your business, say so on your
provider repo — the
applicability map is public and we will correct it.
Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for
this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero:
never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and
several others — scorable at all.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/siteminder: open an issue to ask a question, or submit a pull request to add artifacts.

Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market:
its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted:
not part of the Kin Score or agent readiness.
Registered MCP server and declares compatibility are report only — not weighted.
Undeclared means we found nothing we can read, so there is no number: we never infer integrations.

description: SiteConnect is SiteMinder's integration API for booking channels such as online travel agencies, wholesalers,
global distribution systems, and metasearch partners that contract directly with hotels. The API uses OpenTravel Alliance
message schemas (OTA_HotelAvailNotifRQ, OTA_HotelRateAmountNotifRQ, OTA_HotelResNotifRQ) and is organized into four resource
areas - Rooms and Rates, Availability and Restrictions, Rates, and Reservations - exchanged through both pull and push
patterns over global endpoints. SiteConnect partners must complete SiteMinder's testing and certification program before
gaining production access and become eligible for distribution to properties via individually-negotiated channel contracts.

power custom direct booking flows on their own websites and mobile apps. It exposes property listings, individual property
