Void an invoice
Voids an invoice, marking it as no longer collectable. Accepts an optional void date (defaults to the current date); it may be backdated but must not be in the future or before the invoice’s issue date. Only issued or overdue invoices can be voided: voiding an invoice in any other status returns a 400, and an out-of-range void date returns a 422.
