The following parameters are populated by the Tealium AMP Library. These variables are included automatically in each tracking call from the library and can be used in your Universal Data Hub configuration.
In the following table, some variables are used for both page view/event tracking, while some are only used for each.
For page view tracking, the default event specification for tealium_event is "screen_view". For event tracking, each trigger should specify an event name for tealium_event.
