我正在开发 Global Payments 系统，并尝试实现 Pay By Link http post 方法来生成链接并与客户分享，以便在他们方便的时候付款。在请求正文下方的沙箱 url 中工作正常。

有没有办法启用保存卡选项。我尝试提供在另一个付款参考中看到的以下标志，但响应开始给出哈希错误。
请求正文包括在下面
"CARD_STORAGE_ENABLE": "1",
"OFFER_SAVE_CARD": "1",
"PAYER_EXIST": "0",
"PAYER_REF": "376a2598-412d-4805-9f47-c177d5605853",
"PMT_REF": "ca46344d-4292-47dc-9ced-e8a42ce66977",
以及来自服务器的响应
{
"resultCode":508,
"internalErrorCode":61000,
"errorMessage":"Incorrect hash. Please check your code and the Developers Documentation."
}
这是出于目的的限制还是我们传递了错误的标志？请帮忙！
