Is it possible to get a 3-legged auth without user input ?

https://aps.autodesk.com/en/docs/oauth/v2/tutorials/get-3-legged-token/

I have the below code which triggers the web browser to ask for login and press "allow" button. I can't run autoamted tasks like this, is there a way to call the API in adeffrent way in order to pass my credentials and get authorised programmatically ??

public async Task<string> GetCode()
    {
        
        var requesturl = $"https://developer.api.autodesk.com/authentication/v1/authorize?response_type=code&client_id={client_id}&redirect_uri={redirecturl}&scope=data:create data:read data:write";
        Process.Start(new ProcessStartInfo(requesturl) { UseShellExecute = true });
       
       
        listener = new HttpListener();
        listener.Prefixes.Add(url);
        listener.Start();
        Console.WriteLine("Listening for connections on {0}", url);

        // Handle requests
        Task<string> listenTask = HandleIncomingConnections();

        this.code = listenTask.Result;

        GetToken();
        // Close the listener
        listener.Close();
        return code;

    }

CodePudding user response：

In order to access private user data you need the permission of the user to access it. The way you request permission is with the oauth2 consent screen this is standard part of Oauth2.

So no you cant automate that. AutoDesk-forgue does return a refresh token as part of its oauth2 flow.

What you can do is request authorization once store your refresh token and use the refresh token to request a new access token whenever you need to access the api again.

In this way your automation will run just fine without you.
