Question

I’m testing SkyDrive’s API using the following code:

Dim webRequest As HttpWebRequest = DirectCast(HttpWebRequest.Create("https://apis.live.net/v5.0/me/skydrive/files?access_token=" & Me.ACCESS_TOKEN), HttpWebRequest)
    webRequest.Method = "POST"
    webRequest.ContentType = "multipart/form-data; boundary=A300x"
    webRequest.KeepAlive = True
    webRequest.Timeout = 80000
    Using streamWriter As New System.IO.StreamWriter(webRequest.GetRequestStream())
      streamWriter.Write("--A300x\r\n")
      streamWriter.Write("Content-Disposition: form-data; name=""file""; filename=""HelloWorld.txt""\r\n")
      streamWriter.Write("Content-Type: application/octet-stream\r\n")
      streamWriter.Write("\r\n")
      streamWriter.Write("vooo")
      streamWriter.Write("\r\n")
      streamWriter.Write("--A300x--\r\n")
      streamWriter.Close()
    End Using
    ' response
    Using webResponse As HttpWebResponse = DirectCast(webRequest, HttpWebRequest).GetResponse()
      If webResponse.StatusCode() = HttpStatusCode.OK Then
        Using streamReader As New System.IO.StreamReader(webResponse.GetResponseStream())
          Throw New Exception(streamReader.ReadToEnd())
          streamReader.Close()
        End Using
      End If
      webResponse.Close()
    End Using

Getting bad request (400). Access token and URL are verified & valid. any clue?

If you look at the response body (or use Fiddler to do the same) you’ll find a JSON-formatted error message that explains exactly where the problem lies. My first guess is that the folder skydrive doesn’t exist for this target user.
