plan property
Plan is the tier redeemed against: pro, max or team. It is DERIVED from the org's live ACTIVE/TRIALING subscription, never read from the request, so it is what the org actually holds rather than what it claimed.
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? plan;
