# Data Class

Management of `Data Classes`.

## Find Data Classes

> Finds \`Data Classes\` based on the provided criteria.\
> \
> By default, this endpoint returns a \`basic\` description of the \`Data Classes\` that does not include the details of the \`Classification Rules\`. \
> To retrieve the extended view of the \`Data Classes\` that includes the \`Classification Rules\`, you can pass the \`view=extended\` parameter.<br>
