The Trade Desk generic cookie mapping requires partner identifiers.

The published partner-initiated mapping endpoint carries ttd_pid and ttd_tpi. Their required presence and observable value formats are checked on the generic mapping route.

Customized partner paths and video measurement beacons are separate protocols. Partner account assignment and cookie history require external context.

Apply the contracts within their published source scope.
