OTA_ReadRQ/OTA_ResRetrieveRS	PMS ← SiteMinder (PULL)	Retrieves reservations, modifications, and cancellations

SM_HotelResPaymentReadRQ/RS	PMS ← SiteMinder (PULL)	Retrieves payment transaction details

Supported REST Endpoints

Endpoint	Method & Direction	Purpose
/core-api/pmses/{pmsCode}/hotels/{hotelCode}/room-rates	GET - PMS ← SiteMinder (PULL)	Retrieves all configured room types and rate plans for the specified hotel
/core-api/pmses/{pmsCode}/hotels/{hotelCode}/reservation-import	POST - PMS → SiteMinder (PUSH)	Triggers the import job to retrieve active reservations for the hotel

The REST components of the pmsXchange API only support PMS-level authentication, which means using the same credentials across all properties. If you’re currently using hotel-level authentication (credentials per property), we recommend switching to PMS-level to ensure compatibility with the REST endpoints.

Multiplicity (M)

In the SOAP Specification tables M refers to the number of instances or occurrences of an element or attribute that are allowed or required in a given context. It defines how many times a particular component (element or attribute) can appear within a specific structure.

M	Definition
1	The element or attribute must be present exactly once.
0..1	The element or attribute is optional; it can be present zero or one time.
0..n	The element or attribute can be present zero or more times, with no upper limit (where n represents an infinite number of occurrences).
1..n	The element or attribute must be present at least once and can be present any number of times, with no upper limit.
n..m	Specific range, the element or attribute must be present at least n times and no more than m times (where n and m are specific numbers).
