This document is for developers who use server-side tagging and want to learn more about server-side tagging event parameters.
Google tags use the internal parameters listed on this page. Deleting, augmenting, or modifying these parameters may adversely affect the functionality of Google tags and downstream products (e.g. Google Ads, Google Analytics, Floodlight). The name, type, and products of all event data parameters are subject to change.
