Response message for querying merchant performance.

QueryMerchantPerformanceResponse

JSON representation 
{
  "merchantPerformanceMetrics": [
    {
      object (MerchantPerformanceMetric)
    }
  ]
}
Fields
merchantPerformanceMetrics[]

object (MerchantPerformanceMetric)

The performance data of the merchant.

MerchantPerformanceMetric

JSON representation 
{
  "metricDetail": {
    object (MetricDetail)
  },
  "hourlyMetricValues": [
    {
      object (HourlyMetricValue)
    }
  ]
}
Fields
metricDetail

object (MetricDetail)

Output only. Details of the metric.
hourlyMetricValues[]

object (HourlyMetricValue)

Output only. A list of metric value and its timestamp, rounded to the nearest top of hour.

MetricDetail

JSON representation 
{
  "metricType": enum (MetricType),
  "additionalDetails": {
    string: string,
    ...
  }
}
Fields
metricType

enum (MetricType)

Type of the metric.
additionalDetails

map (key: string, value: string)

Key-value pairs for any additional details about the metric, e.g., "gateway": "stripe". For details see

An object containing a list of "key": value pairs. Example: { "name": "wrench", "mass": "1.3kg", "count": "3" }.

AdditionalDetailsEntry

JSON representation 
{
  "key": string,
  "value": string
}
Fields
key

string
value

string

HourlyMetricValue

JSON representation 
{
  "hourlyTimestamp": string,
  "value": number
}
Fields
hourlyTimestamp

string (Timestamp format)

The timestamp of the metric value rounded to the nearest top of hour.

Uses RFC 3339, where generated output will always be Z-normalized and use 0, 3, 6 or 9 fractional digits. Offsets other than "Z" are also accepted. Examples: "2014-10-02T15:01:23Z", "2014-10-02T15:01:23.045123456Z" or "2014-10-02T15:01:23+05:30".
value

number

The actual metric value. For conversion rate, the value is in the range of [0, 1]. For other metrics, the value is non-negative integer.

Timestamp

JSON representation 
{
  "seconds": string,
  "nanos": integer
}
Fields
seconds

string (int64 format)

Represents seconds of UTC time since Unix epoch 1970-01-01T00:00:00Z. Must be between -62135596800 and 253402300799 inclusive (which corresponds to 0001-01-01T00:00:00Z to 9999-12-31T23:59:59Z).
nanos

integer

Non-negative fractions of a second at nanosecond resolution. This field is the nanosecond portion of the duration, not an alternative to seconds. Negative second values with fractions must still have non-negative nanos values that count forward in time. Must be between 0 and 999,999,999 inclusive.
