How can I check if bid modifier exists, to determine whether to ADD or SET? (C#)

Hi All,

I was just wondering if anyone can think of an easy way to check if the bid modifier already exists in the ad group, because some bid modifiers will need to be created, and some updated.

Cheers

Hi Derek,

You could run a query in the AdGroupBidModifierService and include the field bidModifierSource which will let you know whether there are bid modifiers on the campaign, adgroup levels or if there aren't any.

Cheers,
