title: How to send files from telegram bot?
body: <p>I'm coding a Telegram bot and I need to send files to users. I want to get <code>file_id</code> of files I want to send. I am following <a href="https://stackoverflow.com/a/34366385/10371918">this answer</a>.</p>
  
  <p>To get <code>file_id</code>, I should send the file to my Telegram bot. The question is how to send files via my bot to itself? (maybe using the API?)</p>
