Account Linking
In order to implement the Linking API using the SDK, the developer must extend the servlet class AccountLinkingServlet and implement one abstract method: getUserId.
/**
* Process the request and returns the user id
*
* @param request
* the request relative to the get user id operation
*
* @return a GetUserIdSerializableResponse object
*/
public abstract GetUserIdSerializableResponse getUserId(GetUserIdSerializableRequest
request);
