TripleLift tracker templates preserve their opaque notification payloads.

Published VAST, banner and native response examples establish tracker paths, numeric fields and video progress values. Findings describe those producer templates.

Encoded notification bodies and unpublished endpoint variants remain opaque. Template completeness warnings do not assert an undocumented server rejection rule.

Apply the contracts within their published source scope.
