I need to work with invoice, just after it's payed but already has increment_id.

Is there event after invoice save? Or which function generate increment_id, so i can create plugin on it.

Thanks.

PS: I tried those to observe those two events, but none of them gave me invoice with increment_id.
- sales_order_invoice_register
- sales_order_invoice_pay

Following class is responsible for generating increment_id

Magento/SalesSequence/Model/Sequence.php

/**
 * Retrieve next value
 *
 * @return string
 */
public function getNextValue()

 $this->connection->insert($this->meta->getSequenceTable(), []);
 $this->lastIncrementId = $this->connection->lastInsertId($this->meta->getSequenceTable());
 return $this->getCurrentValue();

So you can use plugin for any modification. Its global function for order, invoice, shipment, creditmemo.

You can pass registry param from

MagentoSalesSequenceModelManager

As an example:

/**
 * Returns sequence for given entityType and store
 *
 * @param string $entityType
 * @param int $storeId
 * @return MagentoFrameworkDBSequenceSequenceInterface
 */
public function aroundGetSequence(
 MagentoSalesSequenceModelManager $subject,
 Closure $proceed,
 $entityType,
 $storeId
)

 // $entityType is 'order' or 'shipment' or 'invoice' or 'creditmemo'
 $this->_objectManager->get('MagentoFrameworkRegistry')->register('sr_entityType', $entityType);
 return $proceed($entityType, $storeId);

Now you get this registry param from getNextValue and modify your own way.

I have a similar requirement, I need to get invoice information after invoice save from admin.


I fulfil the requirement using the event observer.
app/code/Anshu/Customization/etc/adminhtml/events.xml

<?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="AnshuCustomizationObserverAnshuInvoiceSave" />
 </event>
</config>

app/code/Anshu/Customization/Observer/AdminInvoiceSave.php

<?php

namespace AnshuCustomizationObserver;

use MagentoFrameworkEventObserverInterface;

class AnshuInvoiceSave implements ObserverInterface 

 /**
 * @var MagentoFrameworkRegistry
 */

 protected $_registry;

 public function __construct(
 MagentoFrameworkRegistry $registry
 )
 
 $this->_registry = $registry;
 

 public function execute(MagentoFrameworkEventObserver $observer) 
 
 $invoice = $this->getInvoiceObject();
 // My Customization
 

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