To find out what your property's GDS hotel chain and property codes are:
Log in to GDS by SiteMinder.
Go to Setup > Data Management > Distribution Systems.
The Mapping Information will then display for each of the GDS platforms that your property is active on.
The GDS/IDS is displayed in the first column.
The Chain Code in the second column will always be GD. This is the SiteMinder chain code.
The Property Code details are in the third column.
Note: Pegs ADS and Travelweb are currently not supported by GDS by SiteMinder.
