processorRef property
ProcessorRef is the payment processor's own reference. It is the only field that proves money moved at the GATEWAY rather than merely in our ledger, which is why it is answered and not only logged. Absent where the processor returned none.
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;
