如果您需要同时针对不同类型的实体执行操作，或者希望针对单个端点进行写入，而不是针对每个资源类型使用单独的端点，则可以使用 GoogleAdsService.Mutate 端点来执行所有受支持的 变种操作。
Mutate 操作
每个 MutateGoogleAdsRequest 接受一个重复 MutateOperation，每个操作可包含一个资源类型的单个操作。要在单个 GoogleAdsService.Mutate 调用中创建一个广告系列和一个广告组，您需要创建两个 MutateOperation 实体（一个用于 CampaignOperation，另一个用于 AdGroupOperation），然后将两者都传递给 GoogleAdsService。
Ruby
mutate_operation1 = client.operation(:Mutate)
mutate_operation2 = client.operation(:Mutate)
campaign_operation = client.operation(:Campaign)
ad_group_operation = client.operation(:AdGroup)
# Do some setup here to get campaign_operation and ad_group_operation into the
# state you would want them for a regular mutate call to their respective
# services.
mutate_operation1.campaign_operation = campaign_operation
mutate_operation2.ad_group_operation = ad_group_operation
google_ads_service.mutate(customer_id, [mutate_operation1, mutate_operation2])
与其他服务一样，此端点支持部分失败且仅验证。
