I want to get product custom options in ordered items by rest/V1/orders.
If i use searchCriteria, i received all custom options

but in another way i can't resieved custom options. Which method i must extend ?

in my extension i've created file etc/extension_attributes.xml with content

 <?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Api/etc/extension_attributes.xsd">
 <extension_attributes for="MagentoSalesApiDataOrderItemInterface">
 <attribute code="voc_price" type="string"/>
 </extension_attributes>
</config>

create plugin

<type name="MagentoSalesApiOrderRepositoryInterface">
 <plugin name="custom_attributes_voc_discount" type="VendorExtensionPluginOrderGet"/>
 </type>

OrderGet.php

<?php

namespace VendorExtensionPlugin;

use MagentoCatalogModelProductFactory;

class OrderGet

 /** @var MagentoSalesApiDataOrderExtensionFactory */
 protected $orderExtensionFactory;

 /** @var MagentoSalesApiDataOrderItemExtensionFactory */

 public function __construct(
 MagentoSalesApiDataOrderExtensionFactory $orderExtensionFactory,
 MagentoSalesApiDataOrderItemExtensionFactory $orderItemExtensionFactory
 ) 
 $this->orderExtensionFactory = $orderExtensionFactory;
 $this->orderItemExtensionFactory = $orderItemExtensionFactory;
 



 public function afterGet(
 MagentoSalesApiOrderRepositoryInterface $subject,
 MagentoSalesApiDataOrderInterface $resultOrder

 $resultOrder = $this->getExtensionAttributesItem($resultOrder);
 return $resultOrder;
 


 protected function getExtensionAttributesItem(MagentoSalesApiDataOrderInterface $order)
 
 $orderItems = $order->getItems();
 if (null !== $orderItems) 
 /** @var MagentoSalesApiDataOrderItemInterface $orderItem */
 foreach ($orderItems as $orderItem) 
 $extensionAttributes = $orderItem->getExtensionAttributes();
 if ($extensionAttributes && $extensionAttributes->getVocPrice()) 
 continue;
 
 $vocPrice = '5';
 /** @var MagentoSalesApiDataOrderItemExtension $orderItemExtension */
 $orderItemExtension = $extensionAttributes
 ? $extensionAttributes
 : $this->orderItemExtensionFactory->create();
 if($vocPrice) 
 $orderItemExtension->setVocPrice($vocPrice);
 

 $orderItem->setExtensionAttributes($orderItemExtension);
 
 
 return $order;
 



 public function afterGetList(
 MagentoSalesApiOrderRepositoryInterface $subject,
 MagentoSalesModelResourceModelOrderCollection $resultOrder

 foreach ($resultOrder->getItems() as $order) 
 $this->afterGet($subject, $order);
 

 return $resultOrder;
