Google Ads API v24 Simplifies Keyword Forecast Metrics
Google announced Google Ads API v24 (April 2026) which centralizes forecasting infrastructure and updates the KeywordPlanIdeaService.GenerateKeywordForecastMetrics method to focus forecasts on primary metrics tied to bidding strategies. Forecasts will now return a reduced set of metrics aligned to bidding types (e.g., clicks and avg. CPC for Manual CPC/Maximize Clicks; conversions and avg. CPA for Maximize Conversions) and will drop cross-metric and certain secondary fields. v24 also changes request parameters (for example, replacing CampaignToForecast.geo_modifiers[] with CampaignToForecast.geo_target_constants[] and ForecastAdGroup.biddable_keywords[] with ForecastAdGroup.keywords[]) and removes several fields. Google says v24 is available in April 2026 and that Google Ads API v23 is scheduled to sunset in February 2027. Developers are advised to review and update integrations to the v24 parameter set.
Technical release from a major platform (Google) that changes forecasting outputs, request parameters, and sets a sunset for v23 — requiring developer migrations and affecting how search planning integrates with bidding strategies.
