<divid="dev_page_content"><p>We offer three kinds of APIs for developers. The <ahref="#bot-api"><strong>Bot API</strong></a> allows you to easily create programs that use Telegram messages for an interface. The <ahref="#tdlib--build-your-own-telegram"><strong>Telegram API and TDLib</strong></a> allow you to build your own customized Telegram clients. You are welcome to use both APIs free of charge. Lastly, the <ahref="#gateway-api"><strong>Gateway API</strong></a> allows any business, app or website to send verification codes through Telegram instead of traditional SMS.</p>
<p>You can also add <ahref="/widgets"><strong>Telegram Widgets</strong></a> to your website.</p>
<p>Designers are welcome to create <ahref="/animated_stickers"><strong>Animated Stickers</strong></a> or <ahref="/themes"><strong>Custom Themes</strong></a> for Telegram.</p>
<p>This API allows you to connect bots to our system. <ahref="/bots"><strong>Telegram Bots</strong></a> are special accounts that do not require an additional phone number to set up. These accounts serve as an interface for code running somewhere on your server.</p>
<p>To use this, you don't need to know anything about how our MTProto encryption protocol works — our intermediary server will handle all encryption and communication with the Telegram API for you. You communicate with this server via a simple HTTPS-interface that offers a simplified version of the Telegram API.</p>
<p>Bot developers can also make use of our <ahref="/bots/payments"><strong>Payments API</strong></a> to accept <strong>payments</strong> from Telegram users around the world.</p>
<h3><aclass="anchor"name="tdlib-build-your-own-telegram"href="#tdlib-build-your-own-telegram"><iclass="anchor-icon"></i></a>TDLib – build your own Telegram</h3>
<p>Even if you're looking for maximum customization, you don't have to create your app from scratch. Try our <ahref="https://core.telegram.org/tdlib"><strong>Telegram Database Library</strong></a> (or simply TDLib), a tool for third-party developers that makes it easy to build fast, secure and feature-rich Telegram apps.</p>

<p>The Telegram Gateway API allows any business, app or website to send authorization codes through Telegram instead of traditional SMS – offering a powerful and convenient way to <strong>lower costs</strong> while increasing the <strong>security</strong> and <strong>delivery speed</strong> of your codes to Telegram’s 950+ million monthly active users. Users will <strong>instantly receive</strong> messages with codes in a special chat inside Telegram.</p>
