Universal Tag (utag) Debugger
The Universal Tag Debugger (or “utag debugger”) provides an easy way to validate your data layer and tracking calls in real-time as you navigate your site. It’s similar to Web Companion, but is focused on the data captured by each tracking event within utag.js.
The tracking calls made by utag.js are displayed and updated in the tool as you navigate or trigger in-page events.
