Announcing v25.2 of the Google Ads API

trešdiena, 2026. gada 23. septembris

Today we are announcing the release of v25.2 of the Google Ads API. To use the new capabilities, you must upgrade your client libraries and client code. All the updated client libraries and code examples have been published. Come join us for a live walkthrough of this release in our Google Ads API Release Highlights event on Discord or our Ads Developers YouTube Live tomorrow (September 24th at 10am ET). This will also be recorded and posted on YouTube for those who can’t make the live events. If you have any questions or want to discuss this post, reach out to us in the #ads-api channel on Discord. New Features Here are the highlights of what’s new in v25.2:

Competitive benchmarks percentile metrics: BenchmarksService.GenerateBenchmarksMetrics now surfaces metrics representing your competitive standing among other advertisers in percentile tier format using PercentileMetrics and BenchmarksCustomerPercentileTier. You can request this data by adding PERCENTILE_DATA to supplemental_data, setting benchmarks_source to ALL_ADVERTISERS and specifying the category_filter.

Generate Performance Max drafts from Smart campaigns: The new SmartCampaignSettingService.GeneratePMaxDraftCampaign method allows you to programmatically generate a Performance Max draft campaign directly from an existing Smart campaign, simplifying your campaign upgrade workflows.

Asset group URL options: You can now configure tracking templates (tracking_url_template), custom parameters (url_custom_parameters), and final URL suffixes (final_url_suffix) directly at the asset group level on AssetGroup for Performance Max campaigns.

Creator insights by YouTube channel handles: ContentCreatorInsightsService.GenerateCreatorInsights now supports searching directly by YouTube channel handles in addition to channel IDs, streamlining your creator discovery process.

Vertical ads itinerary dimensions and price competitiveness: For hotel and travel advertisers, we've added new itinerary dimension segments (advance_booking_window, length_of_booking, start_date, start_day_of_week, user_set_dates) along with new vertical ads metrics metrics and segments such as vertical_ads_price_difference_percentage, vertical_ads_price_tier and vertical_ads_potential_impressions.

Search bid adjustment recommendations: New recommendations (raise_target_cpa_performance_bid_too_low_recommendation and lower_target_roas_performance_bid_too_low_recommendation) notify you when Target CPA or Target ROAS bids are too low for Search campaigns to enter auctions.
