Google has released version 11.1 of the Google Ads API. Version 11 of the Google Ads API was released in June, so this is a minor update to version 11.

Here is everything that was updated in version 11.1:

Assets

Added AssetGroup.ad_strength to represent the overall quality of the asset group.
When advertisers mutate asset groups or assets associated with the asset groups, this field is recalculated. Until the recalculation is finished, the value is PENDING.
Added AssetLinkError.EXCLUDED_PARENT_FIELD_TYPE.

Audiences

Added FlexibleRuleUserListInfo and RuleBasedUserListInfo.flexible_rule_user_list.
Added more values to the LeadFormFieldUserInputType enum (used as predefined questions for lead form extensions).
Added the following fields to UserAttribute: lifecycle_stage, first_purchase_date_time, event_attribute
Added the following errors to OfflineUserDataJobError: FIRST_PURCHASE_TIME_GREATER_THAN_LAST_PURCHASE_TIME, INVALID_LIFECYCLE_STAGE, INVALID_EVENT_VALUE, EVENT_ATTRIBUTE_ALL_FIELDS_ARE_REQUIRED

Bidding

Added Campaign.bidding_strategy_system_status to show the system status of the bidding strategy, such as whether it is learning, limited, or misconfigured.

Campaigns

Added support for the following metrics in the campaign report: all_conversions_from_click_to_call, all_conversions_from_directions, all_conversions_from_menu, all_conversions_from_order, all_conversions_from_other_engagement, all_conversions_from_store_visit, all_conversions_from_store_website, Made metrics.phone_call compatible with segments.hour in the campaign report.
