在Facebook页面洞察中获取两个奇怪的数字

Question

我正在尝试使用Facebook Graph API获取Facebook页面洞察,我在page_cta_clicks_logged_in_total中看到了一些奇怪的数字(看起来它们会出现在所有logged_in指标中)

以下是来自Facebook的Insight数据示例

{
         "name": "page_cta_clicks_logged_in_total",
         "period": "day",
         "values": [
            {
               "value": {
                  "470946356598165": 0,
                  "156880401338097": 0
               },
               "end_time": "2017-12-13T08:00:00+0000"
            },
            {
               "value": {
                  "470946356598165": 0,
                  "156880401338097": 2
               },
               "end_time": "2017-12-14T08:00:00+0000"
            }
         ],
         "title": "Daily Total CTA click count per Page",
         "description": "Daily: Total CTA click count per Page",
         "id": "<page_id>/insights/page_cta_clicks_logged_in_total/day"
}

什么是数字470946356598165和156880401338097
