Note: The REST API does not return all possible fields for each item by default. Since some response fields are not used by most API users, these fields are suppressed from the response by default in order to reduce latency for the common calls. Additional fields can be enabled in the response using the fields parameters documented in the 'Optimizing API calls for performance' section.
