This object represents a parameter of the inline keyboard button used to automatically authorize a user. It serves as a great replacement for the Telegram Login Widget when the user is coming from Telegram. All the user needs to do is tap/click a button and confirm that they want to log in:

<div class="blog_image_wrap">

<a href="/file/811140015/1734/8VZFkwWXalM.97872/6127fa62d8a0bf2b3c" target="_blank"><img src="/file/811140909/1631/20k1Z53eiyY.23995/c541e89b74253623d9" title="TITLE" alt="TITLE" srcset="/file/811140015/1734/8VZFkwWXalM.97872/6127fa62d8a0bf2b3c , 2x" /></a>

</div>
