  Dim response As String
  Dim request As WebRequest

  request = WebRequest.Create(uri)
  request.ContentLength = jsonDataBytes.Length
  request.ContentType = contentType
  request.Method = method

  Using requestStream = request.GetRequestStream
    requestStream.Write(jsonDataBytes, 0, jsonDataBytes.Length)
    requestStream.Close()

    Using responseStream = request.GetResponse.GetResponseStream
      Using reader As New StreamReader(responseStream)
        response = reader.ReadToEnd()
