Trackingplan Event Data Validation validates analytics and marketing event data as it is collected, rather than after it has reached a warehouse. It inspects real hits, dataLayer payloads, and SDK calls across a large set of analytics and advertising providers. The product flags schema anomalies, missing properties, broken or duplicate triggers, and dropped parameters.

Because checks run continuously against live traffic, regressions surface close to the release that introduced them. It targets the same operational problem as capture-point data quality tooling: stopping malformed event data before it contaminates downstream analysis.
