Error trying to Create ASANA Project in VB.NET - vb.net

I am getting an error:
400 Bad request
when trying to create a project via vb.net in asana.
Note: The ApiKey I am using works when I use it in other vb.net code to get the list of workspaces which is where I got my workspace ID.
Here is my code; I would be grateful for any insight...
Public Sub main()
Dim address As Uri
address = New Uri("https://app.asana.com/api/1.0/projects")
Dim ApiKey As String
ApiKey = "<my api key>"
Dim basicAuthenticationString As String
basicAuthenticationString = Convert.ToBase64String(New UTF8Encoding().GetBytes(ApiKey + ":"))
' Create the web request
Dim request As HttpWebRequest
request = DirectCast(WebRequest.Create(address), HttpWebRequest)
request.Headers("Authorization") = "Basic " & basicAuthenticationString
request.Method = "POST"
request.ContentType = "application/json"
Dim postData As String = "{""data"":[{""name"":""Randy Test Project"",""notes"":""Randy Test Project Notes"",""workspace"":5272875888767}]}"
Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postData)
request.ContentLength = byteArray.Length
Dim dataStream As Stream = request.GetRequestStream()
dataStream.Write(byteArray, 0, byteArray.Length)
dataStream.Close()
Dim response As HttpWebResponse = request.GetResponse()
Console.WriteLine(CType(response, HttpWebResponse).StatusDescription)
dataStream = response.GetResponseStream()
Dim reader As New StreamReader(dataStream)
Dim responseFromServer As String = reader.ReadToEnd()
Console.WriteLine(responseFromServer)
reader.Close()
dataStream.Close()
response.Close()
Exit Sub
End Sub


I was able to figure it out, My address needed to be:
Dim address As Uri = New Uri("app.asana.com/api/1.0/teams/22956925957833/projects")
Then my postData needed to be:
Dim postData As String = "{""data"":{""name"":""Randy Test Project"",""notes"":""Randy Test Project Notes""}}"


Alternatively, you can specify the team or workspace in the post data. When you get a 400 Bad Request the body of the error response will tell you which fields were actually missing/invalid.

VB.NET File upload using WebApi: UnExpected end of MIME

Everything seems to be working except I get this below error in the WEBAPI:
Unexpected end of MIME multipart stream. MIME multipart message is not complete.
When I upload the same file from postman to the WEBAPI endpoint it works perfectly. Makes me think its a problem with the VB application.
BTW: Not skilled in VB (Inherited Application trying to make it work to upload large files)
Dim fileBytes As Byte() = Nothing
Dim boundary As String = "---------------------------" + DateTime.Now.Ticks.ToString("x")
Using binaryReader As New BinaryReader(fileUpload1.PostedFile.InputStream)

binaryReader.Close()
End Using
Dim request As HttpWebRequest =
WebRequest.Create("http://mylocalhost/api/directory")
request.Method = "POST"
request.ContentType = "multipart/form-data; boundary = " + boundary
request.ContentLength = fileBytes.Length
request.Accept = "*/*"
request.AutomaticDecompression = DecompressionMethods.GZip
request.KeepAlive = True
Dim newStream As IO.Stream = request.GetRequestStream()
newStream.Write(fileBytes, 0, fileBytes.Length)
'newStream.Close()
Dim response As WebResponse = request.GetResponse()
' Display the status.
Console.WriteLine(CType(response, HttpWebResponse).StatusDescription)
' Get the stream containing content returned by the server.

Return True````

VB POST request whit form-control values

I am having different problems when trying to make a POST request to my API, the API works perfectly tested in postman.
I would like to know if anyone sees that I am doing wrong, thank you very much
Dim url As String = "http://0.0.0.0/connect"

Dim postdatabytes As Byte()
Dim request As HttpWebRequest = TryCast(WebRequest.Create(url), HttpWebRequest)
enc = New System.Text.UTF8Encoding()
postdatabytes = enc.GetBytes(dataToPassFromFormData)
request.Method = "POST"
request.ContentLength = postdatabytes.Length
Using stream = request.GetRequestStream()
stream.Write(postdatabytes, 0, postdatabytes.Length)

Dim us As user

My api expects these parameters by body / form-data

WebRequest with Bearer Authorization in VB.NET

I would need to send a POST request to a remote server, which requires a Bearer Authorization.
this is my VB.NET code:
Public Shared Function syncAsana() As String
Dim result As String
Try
Dim token As String = "TOKEN"
Dim uri As String = "https://URL/api/1.0/tasks"
Dim postData As String = "assignee=email&notes=TEST_NOTES&name=NOME 1&projects=123985"
Dim byteArray As Byte() = Encoding.UTF8.GetBytes(postData)
Dim request As WebRequest = WebRequest.Create(uri)
request.Method = "POST"
request.PreAuthenticate = True
request.Headers.Add("Authorization", "Bearer " & token)
request.ContentType = "application/x-www-form-urlencoded"
request.ContentLength = byteArray.Length
Dim dataStream As Stream = request.GetRequestStream()
dataStream.Write(byteArray, 0, byteArray.Length)
dataStream.Close()
Dim response As WebResponse = request.GetResponse()
Using dataStream1 As Stream = response.GetResponseStream()
................
result = responseFromServer
End Using
response.Close()
Catch ex As Exception
result = ex.Message
End Try
Return result
End Function
the problem is that I always get the error The underlying connection was closed: An unexpected error occurred on a receive
the same request made with jquery / ajax or with curl works.
I have tried both from the local server launched by visual studio, and by putting the code on the production server.
could you tell me where i'm wrong?

You need to have a cookie container and keep your container with the cookies for subsequent calls. You first do a GET to retreive the security token and/or other cookies then you make other calls like login etc.

Test it out I am not a .net guy. Good Luck!

The cleaner approach is to create a Session for HTTP requests instead of hitting individual api endpoints. In this case the cookies will be sent by default.If you have enough time you can explore AT commands also. Good luck!
