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?
