 <p>Telegram continues to grow worldwide, in part thanks to third-party apps using the Telegram API. To cover the increasing costs that come with this growth, Telegram added <a href="https://promote.telegram.org">sponsored messages</a> – a paid <a href="https://t.me/durov/172">privacy-friendly way</a> to promote <strong>bots and channels</strong>. </p>
-<p>Third-party developers using the Telegam API are required to support and properly display official sponsored messages in their apps by <strong>December 15, 2021</strong>. Unfortunately, Telegram cannot financially sustain third-party apps that do not display sponsored messages and they will have to be disconnected. </p>

 <p>Telegram&#39;s API usage will continue to be <strong>free of charge</strong> for all developers. The <a href="https://core.telegram.org/api/terms#3-advertising-amp-monetization">rules</a> regarding monetization in third-party apps remain the same: developers are allowed to monetize their coding efforts through advertising of their own or other legitimate means, provided that all the methods of monetization used in their apps are prominently mentioned in their app store descriptions.</p>
