What You Can Group & Filter By

Property	Group By (`GroupBy`)	Filter By (`Parameters`)
`day`, `week`, `month`, `hour`	Yes	No
`brandId`, `campaignId`, `optionId`, `creativeId`, `adTypeId`, `siteId`, `zoneId`, `publisherAccountId`, `countryCode`, `metroCode`, `keyword`, `regionCode`, `city`, `modelName`, `brandName`, `osMajorVersion`, `osMinorVersion`, `browser`, `browserMajorVersion`, `browserMinorVersion`, `formFactor`	Yes	Yes

👍
When grouping/filtering by region, you must also group/filter by countryCode.

Important Troubleshooting Notes

Reports that are grouped by Keyword AND Country or Metro AND include a longer than 31 day time span are too large to be queued.
StartDate and EndDate are additional deprecated body params that use MM/DD/YYYY format. However, if you do not have your dates in ISO 8601 format, it's possible to use these params instead. StartDateISO overrides StartDate if different.
If you choose the GroupBy optionId, your report will also be grouped by RateTypeId. This is to break out data on separate lines if your flight changed RateType during the time period.
FlightId will be returned as OptionId in the report.
Reports that GroupBy hour cannot use a time frame longer than 35 days from the present.
You cannot queue a report that groups by or filters by both Keywords and Region or City.
Grouping by any "Device" dimensions does not work for requests. In other words, it is limited to performance reports and is currently not supported for inventory reports.
