Wordpress 2自6月以来，HECKOUT授权失败

从2018年6月初开始，我的大多数客户无法用2支票刷卡付款，以前一切正常

我开始收集回复，它们总是一样的：

"validationErrors":null,
"exception":{
    "errorMsg":"Authorization Failed",
    "httpStatus":"400",
    "exception":false,
    "errorCode":"600"
},"response":null

我不知道发生了什么，我试着联系他们的支持团队，但他们说的一切，一切都应该有效，但实际上没有

我使用API来处理付款。自那时以来，网站代码一直没有更改

对2CO的请求如下所示：

Array
(
    [method] => POST
    [timeout] => 45
    [headers] => Array
        (
            [Accept] => application/json
            [Content-Type] => application/json
        )

    [body] => {
        "sellerId":"my seller id",
        "privateKey":"my private key",
        "merchantOrderId":just a random number,
        "token":"token received from 2CO",
        "currency":"USD",
        "total":"130.00",
        "billingAddr":{
            "name":"name from debit/credit card here",
            "addrLine1":"customer address here",
            "addrLine2":"",
            "city":"customer city here",
            "state":"",
            "zipCode":"",
            "country":"MX",
            "email":"customer email here"
        },
        "lineItems":[{
            "name":"product name here",
            "price":"130.00",
            "type":"product",
            "quantity":"1"
            }]
        }
)

以上是墨西哥客户的示例，因此不需要addrLine2、state和zipCode

提前谢谢你的帮助
