The Change Discovery (OTA_HotelCacheChangeRQ) API is used to query SynXis CR to identify rate and availability changes in SynXis CR, so that the partner can send a targeted shop to SynXis to get the updated availability.

Service Action Code

OTA and Metasearch partners that shop SynXis to cache rates and availability experience reduced shopping volumes and more accurate and up to date availability by implementing Change Discovery Service.

The OTA_HotelCacheChangeRQ/CacheSearchCriteria/@CacheFromTimeStamp is populated with a time and date that occurs in the past. This value is the starting point for which rate and availability changes are requested, ending with the current time of the request. Requests return a value for a maximum of two weeks in the past until the present. Partners are advised to work with Sabre Hospitality Solutions to determine the correct interval of time to use for their needs.

The following attributes are required to define the parameters that are being sent in the query in OTA_HotelCacheChangeRQ/CacheSearchCriteria/

  • CacheSearchCriterion/@HotelCode - contains the valid SynXis Hotel ID.
  • CacheSearchCriterion/@CacheStartDateTime - contains the start date of the range being queried. The earliest possible date is the current date and latest supported date is 3 years from the current date.
  • CacheSearchCriterion/@CacheEndDateTime - contains the end date of the range being queried. The earliest possible date is the current date and latest supported date is 3 years from the current date.

Multiple instances of the CacheSearchCriterion may be used in a message to request different HotelCode instances or different date ranges.
