processorRef property
ProcessorRef is the processor's reference for any card charge — the field that proves money moved at the gateway rather than only in our ledger.
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? processorRef;
