Auto top-up guarantees that your ads will continue to be served without interruption: your account will be credited automatically as soon as funds reach the minimum amount you set.

To enable auto top-up, go to your My Campaigns page, find the Auto top-up block, and click Enable.
If your auto top-op is linked to a Yandex.Money wallet, those funds will be used to credit you advertising account (rather than any bank card that you linked). To avoid having to monitor your wallet balance, set the auto top-up to debit directly from your bank card.
