问题:

My windows service is collect instagram datas from instagram api. I was using client_id but this uses format is removed.

Instagram api is want to access_token but Oauth 2.0 is web-based. or not?

I using .NET and my application type is windows service and web request don't work because this call url: "https://www.instagram.com/oauth/authorize/?client_id=CLIENT-ID&redirect_uri=REDIRECT-URI&response_type=code" is have one more contain redirect. so web response haven't contain my web application link also auto redirect is open..

Steps to get instagram access token register ur application in instagram account. get a client id and client secret.

Step 1: HIT the below url.

https://api.instagram.com/oauth/authorize/?client_id=CLIENT-ID&redirect_uri=REDIRECT-URI&response_type=code

step 2: after hitting above url you will be taken to login page. enter the login credentials and take the code from address bar. it will be live for only 20 seconds i guess.

step 3: The code which you got put it in CODE parameter in the below source code, then run the below code in console application n hit breakpoint at response. you will get access token and userid.

    public void GetDataInstagramToken()
    {
        try
        {
            NameValueCollection parameters = new NameValueCollection();
            parameters.Add("client_id", "CLIENT-ID");
            parameters.Add("client_secret", "CLIENT-Secret");
            parameters.Add("grant_type", "authorization_code");
            parameters.Add("redirect_uri", "REDIRECT-URI");
            parameters.Add("code", "CODE");

            WebClient client = new WebClient();
            var result = client.UploadValues("https://api.instagram.com/oauth/access_token", "POST", parameters);
            var response = System.Text.Encoding.Default.GetString(result);

            // deserializing nested JSON string to object  
            var jsResult = (JObject)JsonConvert.DeserializeObject(response);
            string accessToken = (string)jsResult["access_token"];
        }
        catch (Exception)
        {
           //exception catch
        }
    }
