We are trying to search the inventory using Inventory Search service, we need the list of sites under "Yahoo! Ad Network" so that we can select the sites for which we can search the inventory.
To add further information I am using AccountService.searchForAccount(SearchAccountType.Network, true, "yahoo", 0, 400); To get the Network accounts where "Yahoo! Ad Network" AccountID = 0.
Now to retrive sites under this network I could not find any API. We can get sites under publisher account using SiteService.getSitesByAccountID() Which returns sites under curretly logged in publisher only
