Hi,
I'm using the user sync (http://doc.dynamicweb.com/documentation-8/integration/other/integration-web-services) on a customer where we need to send users from NAV to DW.
In the description it says: "The user must have an ExternalID – this is used when retrieving the user from the Dynamicweb database.". In the NAV-integration I've set the Customer Number to be the key, beacuse we can have multiple users with the same ExternalID. Is it possible to use the Customer number as key in this user sync, instead of the ExternalID?
