轮播广告素材上的 Messenger 广告的 Facebook 广告集创建失败答案

【问题标题】：Facebook Adset Creation Fails for Messenger Ad on a Carousel Creative轮播广告素材上的 Messenger 广告的 Facebook 广告集创建失败
【发布时间】：2017-06-23 12:40:44
【问题描述】：

我正在通过发布到 adsets 端点（营销 API）来创建广告集。它返回给我以下错误：

{
  "error": {
    "message": "An unknown error occurred",
    "type": "OAuthException",
    "code": 1,
    "error_subcode": 1815652,
    "is_transient": false,
    "error_user_title": "Missing Messenger Destination in Child Item",
    "error_user_msg": "To use Messenger as destination, all children     items in the carousel ads should have messenger destination.",
    "fbtrace_id": "AdulKVKescc"
  }
}

广告素材是一个轮播。旋转木马的每个孩子（卡片）都有正确的call_to_action，即'{type:"LEARN_MORE",value:{app_destination:"MESSENGER"}}'

我尝试了在子元素中放置 link 而不是 link 的各种组合。我还尝试放置一个 m.me 链接，但在创建广告素材本身时会引发不同的错误。

我正在使用adcreatives 端点来创建我的广告素材...

关于链接值应该是什么的任何准则？ Facebook 文档说它被忽略了。如果忽略，为什么会出错？

【解决方案1】：

该错误有点误导，因为 child_attachments 都包含 call_to_action，但您还必须将相同的 call_to_action 添加到 link_data 或 video_data 中的广告素材（取决于广告素材的类型）。

将 call_to_action 添加到链接数据。 信贷克里斯西蒙斯

        },
        "page_id": "xxxxxxxxxxx"
    }
}

然后以MESSAGES为目标制作广告系列

def create_campaign(ad_account_id, campaign_name):
my_account = AdAccount(ad_account_id)
campaign = Campaign(parent_id=my_account.get_id_assured())

campaign.update({
    Campaign.Field.name: campaign_name,
    Campaign.Field.objective: 'MESSAGES'
})

campaign.remote_create(params={
    'status': Campaign.Status.paused,
})
logging.debug(campaign)
return campaign.get_id()
