### Method Details

`close()`

    Close httplib2 connections.

`list(filterSetName, pageSize=None, pageToken=None, x__xgafv=None)`

    List all errors that occurred in bid responses, with the number of bid responses affected for each reason.

    Args:
      filterSetName: string, Name of the filter set that should be applied to the requested metrics. For example: - For a bidder-level filter set for bidder 123: `bidders/123/filterSets/abc` - For an account-level filter set for the buyer account representing bidder 123: `bidders/123/accounts/123/filterSets/abc` - For an account-level filter set for the child seat buyer account 456 whose bidder is 123: `bidders/123/accounts/456/filterSets/abc` (required)
      pageSize: integer, Requested page size. The server may return fewer results than requested. If unspecified, the server will pick an appropriate default.
      pageToken: string, A token identifying a page of results the server should return. Typically, this is the value of ListBidResponseErrorsResponse.nextPageToken returned from the previous call to the bidResponseErrors.list method.
      x__xgafv: string, V1 error format.
        Allowed values
          1 - v1 error format
          2 - v2 error format

    Returns:
      An object of the form:

        { # Response message for listing all reasons that bid responses resulted in an error.
      "calloutStatusRows": [ # List of rows, with counts of bid responses aggregated by callout status.
        { # The number of impressions with the specified dimension values where the corresponding bid request or bid response was not successful, as described by the specified callout status.
          "calloutStatusId": 42, # The ID of the callout status. See [callout-status-codes](https://developers.google.com/authorized-buyers/rtb/downloads/callout-status-codes).
          "impressionCount": { # A metric value, with an expected value and a variance; represents a count that may be either exact or estimated (for example, when sampled). # The number of impressions for which there was a bid request or bid response with the specified callout status.
            "value": "A String", # The expected value of the metric.
            "variance": "A String", # The variance (for example, square of the standard deviation) of the metric value. If value is exact, variance is 0. Can be used to calculate margin of error as a percentage of value, using the following formula, where Z is the standard constant that depends on the preferred size of the confidence interval (for example, for 90% confidence interval, use Z = 1.645): marginOfError = 100 * Z * sqrt(variance) / value
          },
          "rowDimensions": { # A response may include multiple rows, breaking down along various dimensions. Encapsulates the values of all dimensions for a given row. # The values of all dimensions associated with metric values in this row.
            "publisherIdentifier": "A String", # The publisher identifier for this row, if a breakdown by [BreakdownDimension.PUBLISHER_IDENTIFIER](https://developers.google.com/authorized-buyers/apis/reference/rest/v2beta1/bidders.accounts.filterSets#FilterSet.BreakdownDimension) was requested.
            "timeInterval": { # An interval of time, with an absolute start and end. # The time interval that this row represents.
              "endTime": "A String", # The timestamp marking the end of the range (exclusive) for which data is included.
              "startTime": "A String", # The timestamp marking the start of the range (inclusive) for which data is included.
            },
          },
        },
      ],
      "nextPageToken": "A String", # A token to retrieve the next page of results. Pass this value in the ListBidResponseErrorsRequest.pageToken field in the subsequent call to the bidResponseErrors.list method to retrieve the next page of results.
    }

`list_next()`

    Retrieves the next page of results.

            Args:
              previous_request: The request for the previous page. (required)
              previous_response: The response from the request for the previous page. (required)

            Returns:
              A request object that you can call 'execute()' on to request the next
              page. Returns None if there are no more items in the collection.
