Adwords API Exclude Content_label on campaign level
问题 I've been researching this for a few hours now and still can't figure out a solution. I intend to exclude some content_labels on the campaign level. At first, I followed the API examples but those are for 'CustomerNegativeCriteria' that are account level settings (sidenote, I couldn't find these global settings on the AdWords interface). Then I read more and tried to exclude them using a CampaignCriterion So I'll create my ContentLabel objects in this way: $criterion = new ContentLabel();
