从Express Checkout获取客户看到的唯一交易ID

Question

我在沙盒帐户上使用PayPal Express Checkout，我正在尝试通过Express Checkout将“客户”paypal网站上的唯一交易ID与已完成的交易相关联。

我的DoExpressCheckoutPayment已退回：

但客户网站说：

发送PayPal Express结账付款（唯一交易ID 7PK53077PJ222701T）

Answer 1

哦......（痛苦的）记忆:)上面提到的“古怪”也存在于其他地方 - 例如易趣交易

IINM，您需要发送自己的“自定义ID” - 上面提到的Invoice Id（显示给最终用户），以便两端都有一些 visual 引用交易。

在REST API中（在Classic中不确定，尚未尝试），如果发送Order，则订单号（最终）在两端共享（两者都相同）。虽然仍然发送你自己的“自定义ID”/“发票ID”也没有坏处。
