Set Campaign Targeting

Sets geographic and language targeting on a campaign. locations: comma-separated location names or geo IDs (a country, cities, or a numeric id such as 2792). negative_locations: locations to exclude. languages: comma-separated language codes (tr, en, de...) or numeric IDs. mode='add' (default) KEEPS the campaign's existing targeting and only adds to it: targeting a city while its country is still targeted does NOT narrow reach, Google takes the union. mode='replace' overwrites: every existing criterion of the dimensions passed (positive locations with locations, exclusions with negative_locations, languages with languages) is removed and replaced with the new list, in a single request so the campaign is never left untargeted. mode='replace' changes a country-wide target into a single-city target. Other dimensions are untouched. A campaign without targeting targets the entire world. confirm=false → preview of the resolved locations + what would be removed.
