Get contacts opted into a preference

Gets contacts who are opted into a given preference

This operation returns an array of up to 1000 contacts who are opted in to a given preference.

If no contacts are opted in to the given preference, an empty array is returned. Otherwise an array containing contact objects is returned.


Preference categories

Results are returned only for preferences, not preference categories.

If you specify the id of a preference category in the path parameter, an empty array will always be returned.
