Dropbox API Support & Feedback
Find help with the Dropbox API from other developers.
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()
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.

Здравко is correct; be sure to refer to the documentation for information on how to properly construct these requests.
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 :
Dim _command As String
_command = "https://api.dropboxapi.com/2/files/list_folder"
Dim Request As HttpWebRequest
Request = HttpWebRequest.Create(_command)
Request.Method = "POST"
Request.KeepAlive = True
ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 Or SecurityProtocolType.Tls12 Or SecurityProtocolType.Tls11 Or SecurityProtocolType.Tls
Request.ContentType = "application/json" ' application/x-www-form-urlencoded"
Request.UserAgent = "Mozilla/5.0 (Windows NT 6.3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36"
ServicePointManager.SecurityProtocol = CType(48, SecurityProtocolType) Or CType(192, SecurityProtocolType) Or CType(768, SecurityProtocolType) Or CType(3072, SecurityProtocolType)
Request.AllowAutoRedirect = True
Request.Headers.Add("Authorization", "Bearer " & token)
Dim payloadLiteral = "{""Path"": ""/files/list_folder""}"
Dim payload = Encoding.UTF8.GetBytes(payloadLiteral)
Request.ContentLength = payload.Length
Using dataStream = Request.GetRequestStream()
dataStream.Write(payload, 0, payload.Length)
End Using
Try
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 Try
Are 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..
I have generate a new token and insered in my web app.
Additional information: Error in call to API function "files/list_folder": request body: unknown field 'Path'
Yes, of course. it's case sensitive! Also, make sure the path is valid... you may start with just empty string - it's always valid.
Perfect, it looks right.
Just a question : i had my token , generate 1 or 2 days ago and that didn't work.
If i go in App console i didn't see it and o i generate again.
How is valid a token ?
should i generate a new one every time i use my web app ?

Access token is short lived, so you may use it for limited time - typically 4 hours or so. If you plan to rely on access token only then, Yes, you will need new every time you are using your application. There is alternative though. 😉 Take a look here for a possible way.
Hope this helps.
