Client ID

A client ID identifies a specific instance of a browser client. A single client ID may be associated with multiple human users if they all use the same browser on the same device. Although it’s conceptually similar to a visitor ID, the client ID is generated on the user’s browser instead of being provided by the Coveo analytics service. It also takes precedence over the visitor ID if both are present when an event is sent.
