3.4.22 Reference Invoice ID

Reference Invoice ID is an invoice-issuer-assigned identifier for an invoice that affects charges as stated on a previous invoice. This occurs typically in the context of credits, refunds, or corrections where an adjustment is applied to a specific previously-issued billing document. This ID allows for direct lineage between adjustments and the original billing records.

ReferenceInvoiceId MUST adhere to the following requirements:

• ReferenceInvoiceId MUST be of type String.
• ReferenceInvoiceId MUST conform to StringHandling requirements.
• ReferenceInvoiceId MUST NOT be null.
• ReferenceInvoiceId MUST match the InvoiceId of the original invoice when it adjusts another invoice.
• ReferenceInvoiceId MUST match the InvoiceId of the current invoice when it does not adjust another invoice.
