Cannot GET access tokens using Authorization code in .net console app, which work in POST MAN

Hi All, I like to seek help on a issue i am facing when i try to authenticate into BOX.

Step 1: i used https://account.box.com/api/oauth2/authorize?response_type=code&client_id="my id"

to get Auth code.

Step 2: i tried to get Access & refresh tokens using postman it worked fine.

Step 3: Now i tried to automate process of getting Access and refresh tokens using .net code.

string param = string.Format("grant_type=authorization_code&code={0}&client_id={1}&client_secret={2}", "mycode", "myid", "mysecret");

var client = new RestClient("https://pfizer.app.box.com/oauth2/token/");

var request = new RestRequest(Method.POST);

request.AddHeader("content-type", "application/x-www-form-urlencoded");

request.AddParameter("application/x-www-form-urlencoded", param, ParameterType.RequestBody);

var response = client.Execute(request);

var json = JObject.Parse(response.Content);

Console.WriteLine(json);

I always get Bad request ,

{ "error": "invalid_grant", "error_description": "The authorization code has expired" }

I am not using auth code 2 times anywhere, even fresh token does not give any response.

Please help.

Thanks.

Hey ,

Curious if there is a gap between when you retrieve the auth code and your first time trying to generate an access token? The reason being the auth code expires after 60 seconds so you will need to make the call to generate an access token before then.

Yeah I made sure I did it before 20 secs.

is it possible to increate the expiration time? 60s is very short!
