Fields enabled for this documentation instance (projection enabled: feature, option, subdomain, closures) plus account-level form field visibility. Role- and user-level field overrides are not applied here, so an API key whose staff user has such overrides may receive fewer fields. A disabled field is omitted from the response object entirely; a present key with a null value means the record simply has no value.
