Google DV360 API: October 2026 Deprecations
Google's Display & Video 360 (DV360) API team announced three unversioned changes taking effect in October 2026 that may impact integrations and structured data file uploads. Effective October 1, 2026, advertisers will no longer be able to exclude specific digital content labels or exclude the majority of sensitive categories via DV360 targeting options and related Structured Data File columns. Effective October 12, 2026, creators must provide a business name and logo when creating or updating YouTube responsive ads if parent-advertiser defaults are not set. The announcement points developers to the DV360 'Announced Deprecations' documentation and a Google Advertising and Measurement Discord community for questions.

Google to Retire Campaign Targeting in DV360 by 2026
Google announced the sunset of Campaign and Insertion Order targeting in the Display & Video 360 (DV360) API and Structured Data Files (SDF) effective February 23, 2026, aligning with removal in the DV360 UI. After that date, API calls retrieving or managing AssignedTargetingOption resources directly under Campaign or InsertionOrder will return 404 errors, and advertisers.lineItems.generateDefault will also return 404. Campaign and Insertion Order targeting columns in SDF downloads will be empty and must be empty on uploads; SDF entries with populated targeting columns will fail to upload. Google points to its DV360 API deprecation documentation for a full list of impacted columns and provides a technical support contact form for help.
What DV360's Brand Suitability Change Means for Campaigns
On October 1, 2026, Google deprecated sensitive categories and digital content labels in Display & Video 360 (DV360) across open web display, video, connected TV, and audio, replacing them with YouTube's unified controls. Advertisers must now select one of three inventory modes and manage ten content themes at the advertiser level, removing granular exclusions for specific categories such as alcohol, tobacco, and weapons. Peer39 highlights that buyers can restore granular, named category controls aligned with industry standards by applying pre-bid contextual categories directly within their DSP.
