Youtube Data API - How to avoid Google OAuth redirect URL authorization

Question

Requirement: I am trying to upload videos to my Youtube channel through Youtube Data API for Java. The request is sent from a war file hosted on tomcat container.My application is not for external users and I only use it to upload my own generated videos. With the help of the api documentation and sample youtube code snippets, I have successfully managed to post video on youtube.

Problem: The issue is that whenever I try to run the code, I get prompted for

Please open the following address in your browser: https://accounts.google.com/o/oauth2/auth?client_id=&redirect_uri=http://localhost:8080/Callback&response_type=code&scope=https://www.googleapis.com/auth/youtube.upload

---

Since I run this code on a remote server, it is not possible for me to always open this URL on the browser. Since I have registered my web app in Google Console, and got a pair of Client ID and Secret and a JSON file, so Youtube must allow me to publish videos by default to atleast my channel, isin't it?

I have used the Auth.java file(provided in youtube java code samples) and the following code is where this thing happens.

    // Authorize.
    return new AuthorizationCodeInstalledApp(flow, localReceiver).authorize("user@.com");

LocalServerReceiver localReceiver = new LocalServerReceiver.Builder().setPort(8080).build();

Please help here as this is really eating up a lot of my development time.

You should only need to authenticate your code once. When your code is authenticated you get a refresh token back. the refresh token will then allow you to get a new access token the next time your code runs.

There is no service account authentication for the YouTube api. Your code has to be authenticated by you the first time in order to get that refresh token.

I am not a java programmer but from a quick check of the documentation it looks quite similar to what I do in.net. You need to create a datastore to to store the first refreshh token then you should be able to run your code in the future with out needing to authenticate it again.
