On success, an array 'invoices' of objects is returned. Each object contains 'label', 'payment_hash', 'status' (one of 'unpaid', 'paid' or 'expired'), and 'expiry_time' (a UNIX timestamp). If the 'msatoshi' argument to lightning-invoice(7) was not "any", there will be an 'msatoshi' field. If the invoice 'status' is 'paid', there will be a 'pay_index' field and an 'msatoshi_received' field (which may be slightly greater than 'msatoshi' as some overpaying is permitted to allow clients to obscure payment paths).
