How to Get OAuth Access Token for Pinterest?

I am accessing Pinterest API for getting user's information by using this url but I can not find that how to generate an access token for Pinterest.

According to this blog post, it says that

Pinterest uses OAuth2 to authenticate users

Can you please tell me, from where I can generate OAuth access tokens for Pinterest?

First, register for an app and set up a redirect URI:

https://developers.pinterest.com/manage/

Then, find your client secret under Signature Tester:

https://developers.pinterest.com/tools/signature/

Bring the user to the OAuth dialog like this:

https://www.pinterest.com/oauth/?consumer_id=[client_id]&response_type=[code_or_token]&scope=[list_of_scopes]

If response type if token, it will be appended as a hash in the redirect URI.

If response type is code, see the post below for details on how to exchange code for token:

What's the auth code endpoint in Pinterest?

You need to register a client app under manager Apps option in Dropdown menu when you login

https://developers.pinterest.com/manage/

This follow the process in this link you have

Hope this helps

**USING C#**

public string GetOAuthToken(string data)
    {
        string strResult = string.Empty;
        try
        {
                string Clientid = WebConfigurationManager.AppSettings["Pinterest_Clientid"];
                string ClientSecret = WebConfigurationManager.AppSettings["Pinterest_ClientSecret"];
                string uri_token = WebConfigurationManager.AppSettings["Pinterest_Uri_Token"];
                System.Net.HttpWebRequest req = (System.Net.HttpWebRequest)System.Net.WebRequest.Create(uri_token);

                string parameters = "grant_type=authorization_code"
                                    + "&client_id="
                                    + Clientid
                                    + "&client_secret="
                                    + ClientSecret
                                    + "&code="
                                    + data;

                req.ContentType = "application/x-www-form-urlencoded";
                req.Method = "POST";
                byte[] bytes = Encoding.ASCII.GetBytes(parameters);
                System.IO.Stream os = null;
                req.ContentLength = bytes.Length;
                os = req.GetRequestStream();
                os.Write(bytes, 0, bytes.Length);
                System.Net.WebResponse webResponse = req.GetResponse();
                System.IO.Stream stream = webResponse.GetResponseStream();
                System.IO.StreamReader reader = new System.IO.StreamReader(stream);
                string response = reader.ReadToEnd();
                Newtonsoft.Json.Linq.JObject o = Newtonsoft.Json.Linq.JObject.Parse(response);
                strResult = "SUCCESS:" + o["access_token"].ToString();                    
        }
        catch (Exception ex)
        {
            strResult = "ERROR:" + ex.Message.ToString();
        }
        return strResult;
    }
