connected property
Connected is true when this org has a stored row for the platform — it has been configured here at least once. It says nothing about whether a credential still resolves; that is Live.
Please note: This property should have been non-nullable! Since the specification file does not include a default value (using the "default:" property), however, the generated source code must fall back to having a nullable type. Consider adding a "default:" property in the specification file to hide this note.
Implementation
bool? connected;
