The only way I know of is to try to modify it. Boost Ads campaigns are the only ones that should product this error.

Hey guys - I got this error trying to add a negative keyword to a campaign. From the documentation: "Attempting to modify a campaign that was created using theGoogle Boost Adsprogram.". The name of the campaign is of the form "Places Ads_someNumber" ... is this a viable way to identify these campaigns? Is there any other way to identify these campaigns?
