url property
URL is the https:// address each matching event is POSTed to. Required, max 2048 bytes; http:// and every other scheme is refused.
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? url;
