REST API - EXAMPLE

Question

Need an example how to make this API call from .NET

 Prefered VB/C#

 

  <form method="POST" action="https://creator.zoho.eu/api/sampleapps/json/sample/form/Employee/record/update"><input type="hidden" name ="authtoken" value="**********"><input type="hidden" name ="scope" id="scope" value="creatorapi"><input type="text" name="criteria" value="Name=Gary"><input type="text" name="Basic" value="20000"><input type="text" name="Address" value="UK"><input type="submit" value="Update Record"></form>

 I tried like this

 

 

Public Function getResponseFromUrl(ByVal url As String, ByVal params As String)
        Dim str As String = ""
        Try
            Dim webreq As HttpWebRequest = WebRequest.Create(url)
            webreq.Method = "POST"
            webreq.ContentType = "application/x-www-form-urlencoded"
            Dim byteArray As Byte() = Encoding.UTF8.GetBytes(params)
            Dim dataStream As Stream = webreq.GetRequestStream()
            dataStream.Write(byteArray, 0, byteArray.Length)
            dataStream.Close()

            Dim res As WebResponse = webreq.GetResponse()
            Dim stream As Stream = res.GetResponseStream()
            Dim streamReader As New StreamReader(stream)
            str = streamReader.ReadToEnd
        Catch ex As Exception
            MsgBox(ex.ToString)
        End Try
        Return str.ToString
    End Function
