google-analytics - Google Analytics Reporting API V4 生命周期值(value)请求 - 无效的维度/指标

Question

我正在尝试调用 Analytics Reporting API V4并在尝试使用某些维度和指标时不断收到不具体的错误消息。例如，我一直得到

{
 "error": {
    "code": 400,
    "message": "Unknown dimension(s): ga:acquisitionTrafficChannel",
    "status": "INVALID_ARGUMENT"
    }
}

通过时ga:acquisitionTrafficChannel ，尽管它是 documented as a valid dimension .同样，我得到

{
 "error": {
  "code": 400,
  "message": "Selected dimensions and metrics cannot be queried together.",
  "status": "INVALID_ARGUMENT"
 }
}

通过时ga:acquisitionSourceMedium ( documented here )，即使没有通过任何指标。

文档过时了吗？其他地方是否有一些关于维度和指标的有效组合的文档？

Answer 1

所有Lifetime Value reports因此 ga:acquisition... dimensions仅对 App views 有效不是 WebView 。

其次，群组/LTV 维度只能在 cohort requests 内查询。例如:

POST https://analyticsreporting.googleapis.com/v4/reports:batchGet
{
 "reportRequests": [
  {
   "viewId": "XXXX",
   "dimensions": [
    {
     "name": "ga:cohort"
    },
    {
     "name": "ga:acquisitionTrafficChannel"
    }
   ],
   "metrics": [
    {
     "expression": "ga:cohortSessionsPerUser"
    }
   ],
   "cohortGroup": {
    "cohorts": [
     {
      "name": "cohort 1",
      "type": "FIRST_VISIT_DATE",
      "dateRange": {
       "startDate": "2015-08-01",
       "endDate": "2015-09-01"
      }
     },
     {
      "name": "cohort 2",
      "type": "FIRST_VISIT_DATE",
      "dateRange": {
       "startDate": "2015-07-01",
       "endDate": "2015-08-01"
      }
     }
    ],
    "lifetimeValue": true
   }
  }
 ]
}

错误消息可能应该更清楚一些。
