Browser information in the atomic event properties

For an overview of the browser information that is tracked in the atomic event properties, please refer to the table on this page.

Context entities added by the tracker

The following context entities are attached at the tracker based on information provided by the browser or operating system.

Browser context

This is an optional feature on the JavaScript tracker that adds browser information that is normally tracked in the atomic event properties (see above) plus some extra information (such as the tab ID) as a context entity.

Context entity: browser_context

How to track?

See the JavaScript tracker documentation to learn how to configure the context entity.

Mobile context

The mobile context entity is tracked on mobile apps gives information about the mobile device platform including some identifiers (IDFA, IDFV). The context entity is enabled by default but the information that is included is configurable on the tracker.

Context entity: mobile_context

Context entities added during enrichment

The following context entities are added during enrichment of events in the pipeline based on other tracked event properties.

YAUAA context for user-agent parsing

YAUAA (Yet Another User Agent Analyzer) enrichment enables parsing the user-agent string tracked in Web events. It extract information about the user's device and browser, like for instance the device class (Phone, Tablet, etc.).
