Request to serwer with soft referenced data asset.

Hi.
I have structure with few properties. On of the property contains soft reference to data asset. In data asset there are stored info about object details, including static mesh, max items etc.
What will happened if I send this structure as param to run on server event, will data asset be send to server in request or data asset will be resolved on server side on demand (if needed)?

Additionally, is it good approach to send this kind structure in server request? Shall I extract only required properties from structure and user only this props in request to minimize size of request?
