Extend the Hierarchy

The Boarding service enables you to build a hierarchy to model your actual business structure or the business structures of your merchants if you are a reseller. You can board a small hierarchy of organizations using only merchant and transacting organizations. You can also use structural organizations to extend the hierarchy. Extending the hierarchy is optional.
Structural organizations can be placed under merchant organizations to represent things like different types of payment systems, different geographical regions, or any other distinction that your business needs. Transacting organizations are then placed under the structural organizations.
