How To Login To Instagram Using The API In VB.NET

Instagram is a photo and video sharing app for smartphones, we can call it a social network. As I said It's a smartphone app but you can view photos, like photos, comment on photos and follow/unfollow users via their website from computer also there are more than 10 popular websites where you can view photos, like photos, comment on photos and follow/unfollow users, browse hashtags and view stats they use the API to do the works.

Without much talk let's get into it..

Remember you're just going to make a Instagram Login, you won't be able to view photos or do anything. You need two textbox and a button you can also add two labels to make it look good. The textbox1 is for username and textbox2 is for password.

Time for some codes...

Required Namespaces :

Imports System.IO
Imports System.Net
Imports System.Text

Functions(We need two functions) :

  
 Dim CC As New CookieContainer
    Dim RQ As HttpWebRequest
    Dim RP As HttpWebResponse
    Public Function GetResponse(ByVal url As String, ByVal referer As String) As String
        RQ = CType(HttpWebRequest.Create(url), HttpWebRequest)
        RQ.CookieContainer = CC

        If referer <> "" Then
            RQ.Referer = referer
        End If

        RP = CType(RQ.GetResponse(), HttpWebResponse)

        Return New StreamReader(RP.GetResponseStream()).ReadToEnd()
    End Function

    Public Function GetResponse(ByVal url As String, ByVal post As String, ByVal referer As String) As String
        RQ = CType(HttpWebRequest.Create(url), HttpWebRequest)
        RQ.Method = "POST"
        RQ.CookieContainer = CC
        RQ.UserAgent = "AppleWebKit/537.36 (KHTML, like Gecko) Mozilla/5.0 (Windows NT 6.1) Chrome/28.0.1468.0 Safari/537.36"

        If referer <> "" Then
            RQ.Referer = referer
        End If

        Dim byteArr() As Byte = Encoding.Default.GetBytes(post)
        RQ.ContentLength = byteArr.Length

        Dim dataStream As Stream = RQ.GetRequestStream()
        dataStream.Write(byteArr, 0, byteArr.Length)

        RP = CType(RQ.GetResponse(), HttpWebResponse)

        Return New StreamReader(RP.GetResponseStream()).ReadToEnd()
    End Function

This code is for your login button :

Dim html As String = GetResponse("https://instagram.com/accounts/login/", "")
        Dim token As String = html.Substring(html.IndexOf("csrfmiddlewaretoken")).Split(""""c)(2)
        Dim username As String = TextBox1.Text
        Dim password As String = TextBox2.Text

        Dim S_B As New StringBuilder
        S_B.Append("csrfmiddlewaretoken=" & token)
        S_B.Append("&username=" & username)
        S_B.Append("&password=" & password)

        html = GetResponse("https://instagram.com/accounts/login/", S_B.ToString, "https://instagram.com/accounts/login/")

        If html.Contains("""username"":""" & username) Then
            MsgBox("Successfully Logged In", MessageBoxIcon.Information)
        ElseIf html.Contains("Please enter a correct username and password.") Then
            MsgBox("Invalid Username or Password", MessageBoxIcon.Error)
        Else
            MsgBox("Unable Login Error", MessageBoxIcon.Error)
        End If

Now run the program and test it..

If you enter correct login credentials you will get this message :
