使用VBA调用FedEx Ship API遇无效JWT问题（已解决：授权链接错误）

已解决！授权时使用了错误的链接，正确的沙箱环境授权链接为：https://apis-sandbox.fedex.com/oauth/token #

我用VBA调用FedEx Ship API时，一直收到错误响应："The given JWT is invalid. Please modify your request and try again."

请求头VBA代码 #

Dim xmlHttp As Object
    Set xmlHttp = CreateObject("MSXML2.XMLHTTP")
    
    xmlHttp.Open "POST", url, False
    xmlHttp.SetRequestHeader "Authorization", "Bearer " & accessToken
    xmlHttp.SetRequestHeader "Content-Type", "application/json"
    xmlHttp.SetRequestHeader "Accept", "application/json"

我能成功获取到accessToken，对比官方示例后没发现格式问题。请求的API地址为：https://apis-sandbox.fedex.com/ship/v1/shipments

收到的完整响应：

{"transactionId": "20479caf-d3d9-4a26-819c-d43f7e91c799","errors":[{"code":"BAD.REQUEST.ERROR","message":"The given JWT is invalid. Please modify your request and try again."}]}

现在怀疑授权环节存在问题：官方示例中的token scope为"cxs"，但我获取到的token scope是"oob"，而且无论输入什么凭证都能拿到token。

获取到的token内容：

{
  "access_token":"826deebc-0788-4bda-995c-e1cb5b588a51",
  "token_type":"Bearer",
  "expires_in":3600,
  "scope":"oob",
  "resource": ["https://apis.fedex.com/*"]
}
