Type | Mechanism/Constraint | Description |
Retry | Retry strategy for communication failure and in case of specific errors returned in XML response | Windsurfer CRS and external channel will have a retry mechanism in place for communication errors and business error. |
Concurrency | Simultaneous connections per property <= 1 | Property at any given time for updating the ARI events, and allows only one connection per property at a time for receiving booking notifications. |
Timeout | Time out after 60,000 milliseconds (1 minute) | Idle connections (no packets sent by either side) for more than one minute are closed. These should be considered as incomplete and implement a retry strategy to re-send data. |
Character Set | Support for UTF-8 | All messages exchanged must have UTF-8 encoding |
Hotels | Only data related to one hotel can be sent in a single request message |
|
Date Range | 720 Days | Maximum number of days that a single request message could update must not exceed 720 days |
Operations - Availability and Inventory
This web service operation allows the Windsurfer CRS to request external channel to update the availability status, inventory count and restrictions of a hotels inventory. Two messages are used in this operation:
OTA_HotelAvailNotifRQ: It is the message sent by the OTA to the external channel to notify of any change in availability.
OTA_HotelAvailNotifRS: In response the external channel sends an OTA_HotelAvailNotifRS message (unless a SOAP level error occurs, in which case a SOAP fault message is sent).
Change Inventory Count
The inventory count update has to be sent separately on room type basis. It means there is only room type and no RatePlan information passed in the RQ message.

Change in Availability Status and Restrictions
Any change in availability status or restrictions update should include both RoomType and RatePlan information.
Windsurfer CRS sends availability status and restrictions update at Product level (i.e. a RoomType + RatePlan). It is possible that multiple products are associated with a single room type.
