如何退款以在Magento中存入貸項憑證？

Question

在Magento中，我試圖創建一個Credit Memo API，並且已經找到了一個好的起點。這允許我創建貸項憑證。用戶能夠從前端完成的一件事，我無法看到如何複製，如果用戶從前端創建貸項憑證，他們會得到一個「退款存儲信用」選項，我需要將其添加到API。你如何將信用備忘錄退還商店信用？在查看Magento中的Creditmemo.php文件時，我沒有看到任何有關爲信用備忘錄創建商店信用的方法。

可以使用的Magento是salesOrderCreditmemoCreate的默認API創建貸項通知單找到。 這裏是一個Magento的商業鏈接，可以幫助你：LINK
