List campaign-level negative keywords

Returns the campaign-level negative keywords (campaign_criterion.negative), distinct from the ad-group-level negatives under GET /v1/ads/keywords. Cached for the quota window (not synced to Postgres), and gated by the shared Google Ads operations budget like every other on-demand Google surface. The response carries cachedAt and stale, set when a quota-exhausted call falls back to the last-good copy instead of a live read.

The platform is always discovered from the campaign itself; a non-Google campaign returns 501 rather than 404, whether or not platform was passed.

Remove a Search keyword

Removes one keyword criterion (positive or negative) from its ad group (M.140).

Replace campaign-level negative keywords

Replaces the FULL set of campaign-level negative keywords (C.270): the desired list is diffed against what Google already has, and the difference is applied as one `create`/`remove` mutate. Send an empty array to clear every campaign negative. The platform is always discovered from the campaign itself; a non-Google campaign returns 501 rather than 404, whether or not `platform` was sent.
