See [Realtime Dimensions](https://developers.google.com/analytics/devguides/reporting/data/v1/realtime-api-schema#dimensions) for the list of dimension names supported by the `runRealtimeReport` method. See [Funnel Dimensions](https://developers.google.com/analytics/devguides/reporting/data/v1/exploration-api-schema#dimensions) for the list of dimension names supported by the `runFunnelReport` method. If `dimensionExpression` is specified, `name` can be any string that you would like within the allowed character set. For example if a `dimensionExpression` concatenates `country` and `city`, you could call that dimension `countryAndCity`. Dimension names that you choose must match the regular expression `^[a-zA-Z0-9_]$`. Dimensions are referenced by `name` in `dimensionFilter`, `orderBys`, `dimensionExpression`, and `pivots`.",
