See the Field Index to learn which calls use includeGroupPropertiesOnly.
If true, the response will include managed values (approved standard values) for certain string-based properties, such as brand or device type. Managed values are not maintained for all properties, but when they are available, they can be used as an enumeration list to create a selection list. When possible, use a managed value to ensure consistent spelling and capitalization.
See the Field Index to learn which calls use includeManagedValues.
