Today, we’re announcing the v5 release of the Google Ads API beta. To use the v5 features, you will need to upgrade your client libraries and client code. The updated client libraries and code examples will be published next week. For more information on breaking changes, see the migration guide.

Here are the highlights:

• Return metrics for entities not formally supported in the API, such as Discovery campaigns, are now available. These entities will show UNKNOWN enum values returned. See the release notes for more details.
• New request parameter to opt into returning all mutable fields in the response during a mutate.
• The API is moving towards using field presence such as optional string and optional double instead of wrapper types such as StringValue and DoubleValue. Your code will be easier to use and simplifies the API with payloads that are significantly smaller. Approximately half of our resources have been updated in this release. The full list is in the migration guide, and our code examples have been updated. The rest of the resources will change to field presence in a future release.
• Subfields of AdGroupAd.policy_summary are now selectable. Non-repeated subfields of AdGroupAd.policy_summary are now filterable.
• Support for Keyword Planner:
  • Added KeywordPlanKeywordHistoricalMetrics.close_variants to return the close variant keywords that have been merged to compute the historical metrics.
  • Added KeywordPlanService.GenerateForecastTimeSeries that returns the weekly forecast trend for Keyword Plan for the next 52 weeks.
