kind property
Kind is the channel and the identity a campaign holds at most one of: paid, organic or email. It picks the executor the launch fans out to.
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
String? kind;
