## POST /api/v2/billing/invoices/{id}/actions/resend-peppol

**Request a Peppol invoice copy**

Queue an explicit copy of an unpaid invoice to its original recipient. Read email-info first and confirm recipientId and transactionId. Reuse requestId for transport retries. The worker fetches the original Qvalia document and uses overwrite=true only for this deliberate copy. It creates no invoice, changes no future preferences and never automatically repeats an ambiguous overwrite. Follow email-info for completion.
