level property
Level is the upline distance from the org whose spend is being shared: 1 is the direct referrer, 2 and 3 the referrers above it. Nothing accrues past 3.
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
int? level;
