Correct registration requires identifying the contract with the advertiser. Check that each contract has the correct type and that the client and contractor are entered in their respective fields. If intermediaries sit between you, the publisher, and the advertiser, enter two contracts: the initial contract between the advertiser and the first intermediary, and the final contract between the intermediary and the publisher. The initial contract is always between the advertiser and the first intermediary in the chain. To determine the contract type, see Help.
If the publisher received the token through Adfox, submit the report in the Adfox interface. For instructions, see Submitting completion certificates in the Adfox interface.
If the publisher received the token from the client or advertiser, submit the data to an advertising data operator (ORD) or through the Yandex ORD account if you have the initial contract details.
