You have to use extension attribute to expose door number at reset Api.

Create an extension attribute on Magento\Sales\Api\Data\OrderAddressInterface for door no field.

Create extension_attributes.xml at app/code/{Vendorname}/{ModuleName}/etc and add door number is an extension attributes.

<?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="Magento\Sales\Api\Data\OrderAddressInterface">
        <attribute code="door_no" type="string" />

I assume that door no is varchar field at the database level.

After that, need to expose this field to using a plugin on on \Magento\Sales\Api\OrderRepositoryInterface . Create after plugin on method save .

namespace Vendorname\ModuleName\Plugin\Magento\Sales\Api;

use Magento\Sales\Api\Data\OrderInterface;
use Magento\Sales\Api\Data\OrderAddressExtensionInterfaceFactory;
use Magento\Sales\Api\Data\OrderAddressExtension;
use Magento\Sales\Api\Data\OrderAddressInterface;

class OrderRepositoryInterface
     * @var OrderAddressExtensionInterfaceFactory
    private $addressExtensionInterfaceFactory;

    public function __construct(
        OrderAddressExtensionInterfaceFactory $addressExtensionInterfaceFactory
    ) {
        $this->addressExtensionInterfaceFactory = $addressExtensionInterfaceFactory;

    public function afterGet(
        \Magento\Sales\Api\OrderRepositoryInterface $subject,
        OrderInterface $order
    ) {
         * @var OrderAddressInterface  $billingAddress
        $billingAddress = $order->getBillingAddress();

        $billingAddressExtensionAttributes = (null !== $billingAddress->getExtensionAttributes())?


        if (!$order->getIsVirtual()) {
            $shippingAddress = $order->getShippingAddress();
            $shippingAddressExtensionAttributes = (null!== $shippingAddress->getExtensionAttributes())?


        return $order;

Create di.xml at app/code/{Vendorname}/{ModuleName}/etc/

<?xml version="1.0" ?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd">

    <type name="Magento\Sales\Api\OrderRepositoryInterface">
        <plugin disabled="false" name="add_door_no_to_address" sortOrder="10"
  • Hi But dont we need di.xml file to be updated? Thanks in advance – poornima Jun 10 '20 at 9:33
  • off course. Di XML is needed... – Amit Bera Jun 10 '20 at 9:34
  • Sorry, It is not working. – poornima Jun 10 '20 at 9:38
  • Am I missing anything – poornima Jun 10 '20 at 9:39
  • Are you implementing this code to existing any module? – Amit Bera Jun 10 '20 at 9:40
