​
Description

Unvoids (reactivates) a previously voided invoice, making it active again. This operation restores the invoice to its pre-void state and, if applicable, restores e-Factura availability if the invoice hasn’t been sent to ANAF.
Important: Only voided invoices can be unvoided. Deleted invoices cannot be recovered as they are permanently removed from the system.

​
Request

The invoice ID to unvoid

​
E-Factura Behavior

When unvoiding a fiscal invoice:
  • If the invoice was not yet sent to ANAF: efactura_available is restored to true
  • If the invoice was already sent to ANAF: efactura_available remains false (cannot resend)
  • Non-fiscal invoices are not affected

Use Cases

​
Accidental Void Recovery

If an invoice was voided by mistake, you can quickly restore it to active status: 
// Accidentally voided the wrong invoice
await api.invoices.void('inv_wrong_one');

// Restore it immediately
await api.invoices.unvoid('inv_wrong_one');

​
Reprocessing Workflow

When you need to temporarily void and then restore invoices for batch processing: 
// Void for processing
await api.invoices.void(invoiceId);

// Do some processing...

// Restore if conditions are met
if (shouldRestore) {
  await api.invoices.unvoid(invoiceId);
}
