I wish to override MagentoCustomerApiDataGroupInterface to add my custom fields.

Custom fields are
1.custom_terms
2.handling_fee

I have created the below file in etc/extension_attribues.xml

<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Api/etc/extension_attributes.xsd">
 <extension_attributes for="MagentoCustomerApiDataGroupInterface">
 <attribute code="custom_terms" type="string"/>
 <attribute code="handling_fee" type="string"/>
 </extension_attributes>

</config>

I have created two additional columns to save my extension attribute values in a customer_group table

My Controller

<?php

namespace PPCCustomerGroupControllerAdminhtmlGroup;

use MagentoCustomerApiDataGroupInterfaceFactory;
use MagentoCustomerApiGroupRepositoryInterface;

class Save extends MagentoCustomerControllerAdminhtmlGroupSave

 protected $groupExtensionInterfaceFactory;
 public function __construct(MagentoBackendAppActionContext $context, MagentoFrameworkRegistry $coreRegistry,
 GroupRepositoryInterface $groupRepository,
 GroupInterfaceFactory $groupDataFactory,
 MagentoBackendModelViewResultForwardFactory $resultForwardFactory,
 MagentoFrameworkViewResultPageFactory $resultPageFactory,
 MagentoFrameworkReflectionDataObjectProcessor $dataObjectProcessor,
 MagentoCustomerApiDataGroupExtensionInterfaceFactory $groupExtensionInterfaceFactory)
 
 $this->groupExtensionInterfaceFactory = $groupExtensionInterfaceFactory;
 parent::__construct($context, $coreRegistry, $groupRepository, $groupDataFactory, $resultForwardFactory, $resultPageFactory, $dataObjectProcessor);
 

 public function execute()
 
 $taxClass = (int)$this->getRequest()->getParam('tax_class');
 $customTerm = $this->getRequest()->getParam('custom_terms');
 $handlingFee = $this->getRequest()->getParam('handling_fee');

 /** @var MagentoCustomerApiDataGroupInterface $customerGroup */
 $customerGroup = null;
 if ($taxClass) 
 $id = $this->getRequest()->getParam('id');
 $resultRedirect = $this->resultRedirectFactory->create();
 try 
 $customerGroupCode = (string)$this->getRequest()->getParam('code');
 if ($id !== null) 
 $customerGroup = $this->groupRepository->getById((int)$id);
 $customerGroupCode = $customerGroupCode ?: $customerGroup->getCode();
 else 
 $customerGroup = $this->groupDataFactory->create();
 
 $extensionAttributes = $customerGroup->getExtensionAttributes();
 $customerExtension = $extensionAttributes ? $extensionAttributes : $this->groupExtensionInterfaceFactory->create();
 $customerExtension->setCustomTerms($customTerm);
 $customerExtension->setHandlingFee($handlingFee);
 $customerGroup->setCode(!empty($customerGroupCode) ? $customerGroupCode : null);
 $customerGroup->setTaxClassId($taxClass);
 $customerGroup->setExtensionAttributes($customerExtension);

 $this->groupRepository->save($customerGroup);

 $this->messageManager->addSuccess(__('You saved the customer group.'));
 $resultRedirect->setPath('customer/group');
 catch (Exception $e) 
 $this->messageManager->addError($e->getMessage());
 if ($customerGroup != null) 
 $this->storeCustomerGroupDataToSession(
 $this->dataObjectProcessor->buildOutputDataArray(
 $customerGroup,
 MagentoCustomerApiDataGroupInterface::class
 )
 );
 
 $resultRedirect->setPath('customer/group/edit', ['id' => $id]);
 
 return $resultRedirect;
 else 
 return $this->resultForwardFactory->create()->forward('new');
 
 

So my problems are below

1. How do I check whether the extension attributes are created or not?


2. The values are not saved in the customer_group table.
   Can anyone guide me if I missed anything?
