Shared account (Account)
The Account object provides automatic distribution of funds between all of an advertiser's active campaigns.
If an advertiser has the shared account enabled, there is no need to add funds to each campaign separately and transfer funds between campaigns. Funds can only be added to the shared account. The cost of clicks for all active campaigns is deducted from the shared account, as well. For more information, see the section Shared account in the Help for Yandex.Direct.
