I am trying to save invoice info in our custom table. So I tried "sales_order_invoice_save_after and sales_order_invoice_pay" events to get invoice data just after creation.

But Observer file didn't getting invoice data, i m using below code in our observer file -

namespace Customcode\Productserialno\Observer\Sales;
class InvoiceSaveAfter implements \Magento\Framework\Event\ObserverInterface

    protected $logger;
    protected $_objectManager;

    public function __construct(
        \Psr\Log\LoggerInterface $logger,
        \Magento\Framework\ObjectManagerInterface $objectManager
            $this->logger = $logger;
            $this->_objectManager = $objectManager;

    public function execute(EventObserver $observer)
            echo "Here in observer";
            $invoice = $observer->getEvent()->getInvoice();
            $order = $invoice->getOrder();
            echo "<pre>"; 
            echo $invoiceId = $observer->getEvent()->getInvoice()->getOrigData('entity_id');
            echo "<pre>"; echo "E";
            if($invoiceId == ''){
                echo "Not found"; 

        } catch (\Exception $e) {
            echo $e->getMessage(); die;

But its not returing any invoice related data, even I checked database there is also not made any new invoice related entry.

Please let me know, what I am doing wrong? Is there is some other "event" I need to use ?

  • Is your function called?

I have a similar requirement, I need to get invoice information after invoice save from admin.
I fulfil the requirement using the event observer.

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="controller_action_postdispatch_sales_order_invoice_save">
        <observer name="observer_admin_invoice_save" instance="Anshu\Customization\Observer\AnshuInvoiceSave" />



namespace Anshu\Customization\Observer;

use Magento\Framework\Event\ObserverInterface;

class AnshuInvoiceSave implements ObserverInterface 
    * @var \Magento\Framework\Registry

   protected $_registry;

    public function __construct(
        \Magento\Framework\Registry $registry
        $this->_registry = $registry;

    public function execute(\Magento\Framework\Event\Observer $observer) 
        $invoice = $this->getInvoiceObject();
        // My Customization

    private function getInvoiceObject()
        return $this->_registry->registry('current_invoice');


Check if it is helpful to you.
Magento version was 2.2.1

  • not working if you create the invoice through API May 21, 2019 at 4:39
  • @FranckGarnier Yes, this will not work if you create invoice through API as I have used the event controller_action_postdispatch_sales_order_invoice_save which is fired when we create invoice through admin-end. May 21, 2019 at 4:53
  • It is a good workaround for admin. May 22, 2019 at 5:30
