Remove account snippet

Detaches a structured snippet from the Google Ads account level, leaving it on any campaigns or ad groups that still use it. Removes the customer_asset attachment only. The underlying shared asset and its campaign or ad-group attachments remain. Fields go in the query string. A JSON body with the same fields is also accepted and, when sent, the query string is ignored.

Create a negative keyword list

Creates a shared Google Ads negative keyword list, optionally with starting keywords; it is not attached to any campaign yet. Creates one Google Ads shared negative keyword list with optional initial keywords in a single atomic mutation. Daily quota is reserved for every mutate item, so large batches may return 429 before any change. This operation is not idempotent. The list is not attached to any campaign.
