Hello Magento Friends,
I hope all are doing great. Today I will be explaining Magento 2: How to Get Order Details with Custom Extension Attributes using REST API. In case you missed reviewing our previous blog, How to Get Region Code by Region ID in Magento 2.
Contents
When customers purchase products, Magento 2 handles various entities, like products, customers, and orders. Magento provides different ways to fetch that entity data. One of them is to Get Order Details using REST API in Magento 2.
But suppose we have used some custom extension attributes with orders or products or customers. In that case, Magento default does not return that custom extension attributes values while we get details using the REST API.
No worries! With the below code’s help, we will learn How to Get Order Details with Custom Extension Attributes using REST API. So let us get started.
Step 1: Create extension_attributes.xml file inside app\code\Vendor\Extension\etc folder and add the code as mentioned below:
<?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\OrderInterface"> <attribute code="delivery_charge" type="decimal" /> <attribute code="payment_charge" type="decimal"/> </extension_attributes> </config>
Step 2: Next create events.xml file inside app\code\Vendor\Extension\etc folder and add the below code:
<?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="sales_order_load_after"> <observer name="sales_order_load_attribute" instance="Vendor\Extension\Observer\OrderLoadAfter"/> </event> </config>
Step 3: Next create OrderloadAfter.php file inside app\code\Vendor\Extension\Observer folder and add the below-mentioned code:
<?php namespace Vendor\Extension\Observer; use Magento\Framework\Event\ObserverInterface; class OrderLoadAfter implements ObserverInterface { protected $_orderExtension; public function __construct(\Magento\Sales\Api\Data\OrderExtension $orderExtension) { $this->_orderExtension = $orderExtension; } public function execute(\Magento\Framework\Event\Observer $observer) { $order = $observer->getOrder(); $extensionAttributes= $order->getExtensionAttributes(); if ($extensionAttributes === null) { $extensionAttributes = $this->_orderExtension; } $deliverycharge = $order->getData('delivery_charge'); $paymentcharge = $order->getData('payment_charge'); $extensionAttributes->setData('delivery_charge',$deliverycharge); $extensionAttributes->setData('payment_charge',$paymentcharge); $order->setExtensionAttributes($extensionAttributes); } }
Step 4: Next clear the generated folder from Magento root and clear cache.
Step 5: Finally, execute the getOrderDetails.php script file inside your Magento root folder and add the below code. (You can use this code in your Magento file system. e.g., you can even use it in your custom module).
<?php $userData = array("username" => "admin", "password" => "adminPassword"); $baseUrl = "http://domain.com/index.php"; // your magento base url $ch = curl_init($baseUrl."/rest/V1/integration/admin/token"); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST"); curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($userData)); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Content-Lenght: " . strlen(json_encode($userData)))); $token = curl_exec($ch); $ch = curl_init($baseUrl."/rest/V1/orders/1"); curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "GET"); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Authorization: Bearer " . json_decode($token))); $result = curl_exec($ch); $result = json_decode($result, 1); echo '<pre>';print_r($result);?>
That’s it!

I want to display order attribute value outside 'extension_attributes' level.. it means display order attribute value at the top level of order rest API response.
I added a custom product attribute via code, and implemented the above solution, but the custom attribute is NOT visible in the API response.
How do I get a custom product attribute to show in the order API?
The blog is about the Order Attribute, not the product attribute
