Remove a Search keyword

Removes a single keyword or negative keyword from a Google Search ad group.

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

Path Parameters

keywordId*string

Zernio keyword ID (id), or Google's native {adSetId}~{platformCriterionId} (the tail of resourceName, e.g. 1234567890~987654321). A bare criterion id is rejected because it is only unique within its ad group.

Pause or enable a Search keyword

Pauses or re-enables a single Google Search keyword. Changes `ad_group_criterion.status` for one keyword criterion (M.140). Negative keywords have no status on Google and cannot be paused or enabled.

List campaign-level negative keywords

Lists the negative keywords set on a whole Google campaign, separate from ad group negatives. 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.
