It is currently only possible to query undelivered reservations per hotel. Undelivered identifies all reservations, modifications or cancellations which have not been previously acknowledged with an OTA_NotifReportRQ message by the PMS.
The exchange involves 4 5 different messages:
- Using the OTA_ReadRQ message, the PMS will request reservations, modifications or cancellations from pmsXchange.
- Using the OTA_ResRetrieveRS message, pmsXchange will return reservations, modifications or cancellations which meets the requested criteria.
- The PMS will process the response and send an OTA_NotifReportRQ with success or errors after processing.
- PmsXchange will then respond with an OTA_NotifReportRS to acknowledge the receipt.
- Using the OTA_HotelAvailNotifRQ, the PMS sends pmsXchange back the affected 'Availability' change.
