php - 您如何退款以在 Magento 中存储贷记凭证？

Question

在 Magento 中，我正在尝试创建 Credit Memo API，并且已经找到了一个很好的起点。这让我可以创建贷项通知单。用户可以从前端做的一件事我看不到如何复制是如果用户从前端创建信用凭证他们会得到一个“退款到商店信用”选项我需要添加到应用程序接口(interface)。如何将贷项通知单退还至商店贷项？在 Magento 中查看 Creditmemo.php 文件时，我没有看到任何与为信用凭证创建商店信用有关的方法。

下面是我在Magento论坛上找到的credit memo API

您可以使用 magento 的默认 API 创建 Credit Memo，即 salesOrderCreditmemoCreate。 这是一个可能对您有帮助的 magento 商务链接:LINK

public function create($orderIncrementId, $creditmemoData = null, $comment = null, $notifyCustomer = false,
    $includeComment = false, $refundToStoreCreditAmount = null)
{
    /** @var $order Mage_Sales_Model_Order */
    $order = Mage::getModel('sales/order')->load($orderIncrementId, 'increment_id');
    if (!$order->getId()) {
        $this->_fault('order_not_exists');
    }
    if (!$order->canCreditmemo()) {
        $this->_fault('cannot_create_creditmemo');
    }
    $creditmemoData = $this->_prepareCreateData($creditmemoData);

    /** @var $service Mage_Sales_Model_Service_Order */
    $service = Mage::getModel('sales/service_order', $order);
    /** @var $creditmemo Mage_Sales_Model_Order_Creditmemo */
    $creditmemo = $service->prepareCreditmemo($creditmemoData);

    // refund to Store Credit
    if ($refundToStoreCreditAmount) {
        // check if refund to Store Credit is available
        if ($order->getCustomerIsGuest()) {
            $this->_fault('cannot_refund_to_storecredit');
        }
