### Reservations

`SOAP/XML` - When a reservation is created, modified, or canceled in the **partner PMS application** (Reservation Uploader/Data Publisher) and pushed to **SiteMinder Exchange**, SiteMinder generates a notification for each reservation event. These notifications are then **pushed** to subscribing SMX partner applications.

Subscribing SMX partner applications can use the reservation data to deliver value-added solutions for the hospitality and travel industries.
