不幸的是，它还没有在Magento_Sales：：sales中实现，但是你可以扩展你自己的API。https://github.com/magento/magento2/issues/3552

对于获取客户订单历史记录，使用searchCriteria并传递customer_email id。
按照下面的Magento 2 API获取客户订单历史记录。
请求URL：https://magento.com/rest/V1/orders?searchCriteria[filter_groups][0][filters][0][field]=customer_email&searchCriteria[filter_groups][0][filters][0][value]=test@gmail.com
方法：GET

Magento默认顺序API与管理员进行身份验证。如果您想与客户进行身份验证。
请创建一个新的自定义模块，然后创建自己的新API端点。
在Vender\Module\etc\webapi.xml文件中添加新的API端点。

<!--Get Order by ID-->
<route url="/V1/ca-orders/:id" method="GET">
    <service class="Magento\Sales\Api\OrderRepositoryInterface" method="get"/>
    <resources>
        <resource ref="self" />
    </resources>
</route>
<!--Get Order list-->
<route url="/V1/ca-orders" method="GET">
    <service class="Magento\Sales\Api\OrderRepositoryInterface" method="getList"/>
    <resources>
        <resource ref="self" />
    </resources>
</route>

现在你可以使用url http://magento.local/index.php/rest/V1/ca-orders?searchCriteria和客户认证令牌。
