This specification is intended for external partners integrating with the Bango Digital Vending Machine that need to issue refunds as part of consumer offer lifecycle management. It assumes familiarity with RESTful APIs, JSON/YAML schema definitions, and standard HTTP response semantics. The refund models defined here are foundational DVM components and should be treated as stable, reusable contracts rather than product-specific implementations.

Early Access Notice
This specification is provided as part of an Early Access release. The models and interfaces described here may evolve as the Digital Vending Machine continues to develop. While changes are expected to be incremental, integrators should be aware that updates may be introduced over time.
