Session attribute data is forwarded from the Canisters to the cxReveal server using the Event Bus, a component of cxConnect for Data Analysis.

The Event Bus is used for delivering event information to third-party consumers of the data. cxReveal utilizes this functionality to capture additions or changes to session attribute information, which is automatically tracked in each Canister.

Before you begin, you should familiarize yourself with the Event Bus and how it works.
