# Data Types
The new API docs can be found here: [https://apidocs.mediamath.com/apis/reporting-api](https://apidocs.mediamath.com/apis/reporting-api)
The `id` type allows any character except whitespace.
The `datetime` type may be filtered by dates, or datetimes in either of the following ISO 8601 based formats.
* date - YYYY-MM-DD
* datetime - YYYY-MM-DDThh:mi:ss

Year, month, and day are all 1-based.  Hour, minute, and second are all 0-based.  Valid hours are 0-23.
The dimension fields of the `datetime` type will always be output in the aforementioned datetime format.  The output columns for the time field will be output in the same format, but without the separating 'T'.
