# Cancel Invoice Sample

This sample code demonstrate how you can cancel an invoice.

/** @var Invoice $invoice */ $invoice = require 'SendInvoice.php'; use PayPal\Api\Invoice; use PayPal\Api\CancelNotification; try {

### Cancel Notification Object

This would send a notification to both merchant as well the payer about the cancellation. The information of merchant and payer is retrieved from the invoice details

$notify = new CancelNotification(); $notify ->setSubject("Past due") ->setNote("Canceling invoice") ->setSendToMerchant(true) ->setSendToPayer(true);

### Cancel Invoice

Cancel invoice object by calling the static `cancel` method on the Invoice class by passing a valid notification object (See bootstrap.php for more on `ApiContext`)

$cancelStatus = $invoice->cancel($notify, $apiContext); } catch (Exception $ex) { ResultPrinter::printError("Cancel Invoice", "Invoice", null, $notify, $ex); exit(1); } ResultPrinter::printResult("Cancel Invoice", "Invoice", $invoice->getId(), $notify, null);
