Negative Keywords

Lists ALL negative keywords that apply to the account: ad-group level, campaign level AND the SHARED negative keyword lists (Shared Library) attached to campaigns. If campaign_id is empty it covers the whole account; if given, it covers that campaign plus the shared lists attached to it. Every row carries `level` (ad_group | campaign | shared_list) so you know where to remove it from. It lists the negatives already in place, so a term covered here is already blocked. Every matching negative and every shared-list-to-campaign attachment is retained in the single `negatives` collection: `record_type=negative` is a removable keyword and `record_type=shared_list_campaign` states where a shared list applies. `limit` controls only this response page and `page_token=next_page_token` reads the cached continuation without another Google Ads query or credit. Read-only.
