ReimbursementRequest : The reimbursement process is used to support refunds which are not covered by the online refund/exchange processes, e.g.: Partial refund of a trip (Trip was Hamburg - Munich, but only Hamburg - Kassel was used), Refund outside of rules due to good will. This is a manual back office process within the provider’s organization which is triggered by this request. State changes can be signaled by web hook events.
