For day to day usage, when ARI changes are made, the PMS provider must ensure that only changes to rates, and not full refreshes, are sent. Full refreshes should only be sent at most once per day and at times when traffic is low i.e. between midnight and 5 am. Only in exceptional circumstances should additional full refreshes be sent.
Identical changes in rates for consecutive days should be condensed into one message wherever possible. For instance, if the change in rates counts for room type SGL is = $100 for Jan 1st, Jan 2nd and Jan 3rd, the PMS provider should send one single message to pmsXchange with start date Jan 1st and end date Jan 3rd rather than 3 messages.
The PMS will need to establish transaction/error logs to collect error messages generated by the system in case of errors in the transmission of your upload messages. The error log and error messages must be available to the property user for regular checks. For example, if a rate message is rejected by pmsXchange because of erroneous content (for instance if it contains a rate code that is not recognised by pmsXchange the PMS provider must ensure such message is made available for the property to view and that the property is alerted the transaction was not successful. Upon viewing the error message the property and/or PMS must ensure the appropriate correction is applied as soon as possible and ideally no later than 12 hours from receipt of the message. If no corrective action is taken, and the incorrect message continues to attempt to upload in a loop, SiteMinder will reserve the right to disable the interface till such time as corrective action is taken.
It is advisable that the PMS has a queuing mechanism that queue upload messages in case of lack of connectivity with the pmsXchange service or during scheduled release outages. If pmsXchange fails to respond at all, then the messages should be re-sent when connectivity is re-established.
pmsXchange v2 only allows Rate Updates for Room/Rate code combinations that are known to SiteMinder (i.e. have been setup and mapped to the PMS within the SiteMinder Channel Manager). If we receive an Inventory Update that contains a Room/Rate code that is unknown to SiteMinder Channel Manager, the entire Update will fail.
PMS Payment Transaction Sync
...
The SiteMinder Pay integration with Channel Manager & Property Platform offers customers the ability to process payments for their Channel and Direct Booking reservations, and secure their funds effectively. Currently, customers have to manually record these payments in their respective PMSs. However, Siteminder is launching a new PMS-Pay Transaction Sync feature that enables SM payment transactions associated with a CM reservation in CM or Property Platform to be passed automatically to participating PMSs as a separate "Payment Transaction". This removes the manual effort required to record payments processed by SM Pay to the customer’s PMS, improving user experience and reducing time spent on managing payments. This feature will increase adoption and transaction volumes for us going forward.
