我想开发一个系统，例如将产品从我的站点导出到 ebay 站点。我创建了开发者帐户并获得了将产品添加到 ebay 的示例代码。我从https://www.x.com/developers/eBay/documentation-tools/code-sample/219177获得了 PHP 示例代码。我在示例代码中添加了沙盒 API 详细信息，当我运行代码时出现此错误：
eBay returned the following error(s):
21916250 : Return policy is not specified.
A return policy must be specified.
我是 ebay 集成的新手？如何在 ebay 示例代码中指定退货政策。我正在添加示例代码供您参考：
<?php require_once('../get-common/keys.php') ?>
<?php require_once('../get-common/eBaySession.php') ?>
