atPeriodEnd property
AtPeriodEnd cancels at the end of the paid period rather than at once. It defaults TRUE on the endpoint, because a customer who cancels has already paid for the period they are in.
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? atPeriodEnd;
