Information Messages

Personalized information such as news, personal communications, product details, or entertainment are not particularly time-sensitive and do not initiate changes in any entity or user state. However there is value in keeping the contents of this communication private from unintended observers. The client will initiate a request for this information and the server will respond.

This communication occurs between a trusted services network client and server.
