Retrieves the previously-recorded additional data field against an unprocessed web client, employer, employee or contact. 

This is used to set other non-standard fields in a processed web enrolment. The format of the data is to be an XML string. This contains essentially name-value pairs, mapping additional data field names to values. 

The recordType parameter is an indentifier of what type of record to update (web client, employer, employee or contact). The recordId parameter is the ID of the record of that type to update. The additional data can be set by calling UpdateAdditionalDataForWebRecord. 

A token is passed for authentication. If the authentication fails, or other errors occur, the additional data field is not retrieved. The result of the authentication is represented by a TAuthenticate object. 

Requires a valid registration key entry for the Short Courses feature. 

This function has security level "Protected", and can only be accessed by users that have explicitly been granted permission to the API.
