Access dropbox file - Authentication failed because the remote party has closed the transport stream
i'm new in this type of access.
I wrote this code but i have the error in objet to recover the list of files in dropbox.
Dim token As String
token = "sl.B6........."
Dim _command As String
_command = "https://api.dropboxapi.com/2/files/list_folder"
Dim Request As HttpWebRequest
Request = HttpWebRequest.Create(_command)
Request.Method = "GET"
Request.KeepAlive = True
Request.ContentType = "application/json"
Request.UserAgent = "Mozilla/5.0 (Windows NT 6.3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36"
Request.AllowAutoRedirect = True
Request.Headers.Add("Authorization", "Bearer " & token)
ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12
Dim Response As HttpWebResponse = Request.GetResponse()

Здравко is correct; be sure to refer to the documentation for information on how to properly construct these requests.
The endpoint for folder listing is RPC call style endpoint. RPC on Dropbox uses POST request and it's mandatory 'path' to be passed in JSON style to the request body. Fix your code.
Good luck.
Thank you.
It's first time that i use this tools.
I changed the Metod in POST and insered the path ( looking other example ) but i have always error 401 not autorized.
this is new cod :

dataStream.Write(payload, 0, payload.Length)
End UsingTry
Using response = CType(Request.GetResponse(), HttpWebResponse)
Using reader = New IO.StreamReader(response.GetResponseStream())
'Return reader.ReadToEnd()
End Using
End Using
Catch ex As WebException
Using response = CType(ex.Response, HttpWebResponse)
Using reader = New IO.StreamReader(response.GetResponseStream())
Throw New Exception(reader.ReadToEnd())
End Using
End Using
Catch ex As Exception
Throw
End TryAre you sure the access token you're using is actual one and not expired? 🧐
Also, post the received result (either error or success) so it be clear what's going on exactly..
