Try to get instagram API

Question

I need some help, i try to get instagram api in my application( windows forms) but not success.My code is like this:

using (var wb = new WebClient())
{
    var data = new NameValueCollection();
    data["client_id"] = "client_id"; 
    data["client_secret"] = "client_secret";
    data["username"] = "user"
    data["password"] = "pass"
    data["grant_type"] = "password";

But after run this give me the error:

{
"code": 400,
"error_type": "OAuthException",
"error_message": "This client is not xAuth enabled"
}

Answer 1

From the description of the error the values you are passing in for data["client_id"] and data["client_secret"] are not authorized to use the API. Make sure you have registered your application and you are using the correct two values that where given to you during your registration.

Also check that your app is authorized to use data["grant_type"] = "password";. From reading their API password based authentication is not allowed, you must use "redirect based" authentications to be able to authenticate with their API.

EDIT: Found this in the documentation under Step 3 for server side authentication

grant_type: authorization_code is currently the only supported value

So your grant type of password and passing the username and password is definitely the problem.
