Hi,
Sorry to dig up an old thread, but I was wondering the same thing.
I'm trying to do this in Python for a customer of ours; I want to use the API to target a line item on Run of Network.
I do not want to select an ad unit that inherits all children (for this customer I can not create ad units); I want to be able to literally Run of Network.
Is this possible with the API?
Thanks in advance,
Sander
