Youtube API application

I need an application, which given a youtube link, it should report/flag the youtube video with a given reason (spam/scam/misleading content) through the youtube API passing through a proxy taken from https://proxyscrape.com/free-proxy-list.

This is the youtube API to use: https://developers.google.com/youtube/v3/docs/videos/reportAbuse

The application should be written in C#.NET
