External Reference ID

An external reference ID (externalReferenceID) is a unique identifier that references a shopper or product on a remote system owned by a company. You can use an external reference ID to reference either a shopper or a product, depending on the context.

The Remote User Management (also known as SSO) service requires an externalReferenceID. The externalReferenceID must be unique per user because it is used across several different objects. Failure to do so may violate your contract with Digital River and will cause users to get cross-linked. In fact the entire inbound userKey (in the response to LoginRequest, GetUserRequest) MUST be unique per user in clients database.
