When the customer sends a quote for any product, it is essential for Magento 2 store owners to get quote information.

Previously we have discussed How to Get Quote Information using REST API in Magento 2.

But if we have used custom extension attributes, default Magento does not return its value. To get quote Details with Custom Extension Attributes value using REST API in Magento 2, use the below steps.

Steps to Get Quote Details with Custom Extension Attributes value using REST API In Magento 2:

Step 1: Firstly, go to the below path

app\code\Vendor\Extension\etc\extension_attributes.xml

And add the code as follows:

<?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\Quote\Api\Data\CartInterface">
        <attribute code="customattribute" type="string" />
    </extension_attributes>
</config>

Step 2: Now go to the below path 

app\code\Vendor\Extension\etc\di.xml

And add the code as given below:

<?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\Quote\Api\CartRepositoryInterface">
        <plugin name="cart_extra_attribute" type="Vendor\Extension\Plugin\Cartrepositoryplugin" />
    </type>
</config>

Step 3: Then, move to the below path

app\code\Vendor\Extension\Plugin\Cartrepositoryplugin.php

And add the code as below:

<?php
namespace Vendor\Extension\Plugin;

use Magento\Quote\Api\Data\CartExtensionFactory;
use Magento\Quote\Api\Data\CartInterface;
use Magento\Quote\Api\Data\CartSearchResultInterface;
use Magento\Quote\Api\CartRepositoryInterface;
use Magento\Framework\Exception\CouldNotSaveException;

class Cartrepositoryplugin
{
    protected $extensionFactory;

    public function __construct(CartExtensionFactory $extensionFactory)
    {
        $this->extensionFactory = $extensionFactory;
    }
     public function afterGet(CartRepositoryInterface $subject, CartInterface $quote)
    {
        $customattribute = $quote->getData('customattribute');
        $extensionAttributes = $quote->getExtensionAttributes();
        $extensionAttributes = $extensionAttributes ? $extensionAttributes : $this->extensionFactory->create();
        $extensionAttributes->setData('customattribute',$customattribute);
        
        $quote->setExtensionAttributes($extensionAttributes);
        return $quote;
    }
}

Step 4: Lastly, create getquotedetails.php in the Magento root directory and add the below code:

<?php
 $admindata = array("username" => "admin", "password" => "admin@123");
 $baseUrl = "http://yourdomain"; // 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($admindata));
 curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
 curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json", "Content-Lenght: " . strlen(json_encode($admindata))));

 $token = curl_exec($ch);

 $ch = curl_init($baseUrl."/rest/V1/carts/1"); // change cart id 
 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);
?>

After that run URL as below:
