Seamless Web3 Authentication: Cryptographic Wallet Proof Signature, Manifest Specs & Frictionless Jetton Transfers
Telegram Mini Apps (TMA) have rapidly evolved from simple in-chat web overlays into full-fledged mobile applications that compete directly with native App Store and Google Play binaries. Historically, mini-apps were confined within a chat window, burdened with visible header banners, back buttons, and close crosses that reminded users they were operating inside a messaging client. With the release of the TMA Fullscreen Mode API, Device Orientation Locks, and Add-to-Home-Screen (WebAPK) Infrastructure, developers can now deliver an indistinguishable native mobile user experience. Web3 games, DEX terminals, and enterprise dashboards can capture 100% of the viewport, leverage tactile haptic vibration engines, and install directly to the user's home screen. This guide provides the complete SDK implementation blueprint.
Fullscreen Canvas Ingest
Invoking requestFullscreen() to eliminate chat headers, status bars, and UI chrome, capturing 100% of edge-to-edge screen real estate.
Device Orientation Lock
Locking hardware viewport to portrait or landscape orientations via lockOrientation(), essential for AAA games and trading terminals.
Home Screen WebAPK Deploy
Deploying one-click home screen shortcuts through addToHomeScreen(), giving users direct app launch capability without opening chat.
Tactile Haptic Engine
Triggering native smartphone vibration motors via HapticFeedback API, providing tactile mechanical feedback for clicks and success states.
1. Operational Step-by-Step: Integrating the Native TMA SDK APIs
Mount Latest Telegram WebApp SDK Script
Include the official script inside your application HTML <head>: <script src="https://telegram.org/js/telegram-web-app.js"></script>. Confirm that window.Telegram.WebApp.version reports v7.10 or higher to ensure fullscreen support.
Invoke Fullscreen Mode & Lock Orientation
Upon component mount, call Telegram.WebApp.requestFullscreen(). To prevent unwanted screen flipping during gameplay, immediately call Telegram.WebApp.lockOrientation('portrait') (or 'landscape' for wide console games). Listen to the fullscreen_changed event for responsive CSS reflows.
Prompt Users to Install Home Screen Shortcut
Query Telegram.WebApp.checkHomeScreenStatus(callback). If status is 'missed', present a polished in-app banner inviting users to install your app. When clicked, call Telegram.WebApp.addToHomeScreen(). Android compiles a native WebAPK with its own application icon in the app drawer.
Engage Tactile Haptic Feedback Triggers
Elevate user immersion by firing mechanical haptics on user actions: Telegram.WebApp.HapticFeedback.impactOccurred('medium') on button taps, and Telegram.WebApp.HapticFeedback.notificationOccurred('success') upon transaction confirmations.

4. Development Edge Cases & FAQ
help What happens if a user clicks an external link while in TMA Fullscreen Mode?
You should invoke Telegram.WebApp.openLink(url) or Telegram.WebApp.openTelegramLink(url). Never navigate standard window.location.href to external domains directly within the WebApp canvas, as doing so breaks the Telegram bridge and dismisses fullscreen mode.
help Does the WebAPK require approval from the Google Play Store?
No. Telegram's addToHomeScreen architecture generates an autonomous WebAPK wrapper signed directly by the local device operating system or browser service worker. Developers enjoy 100% permissionless continuous deployment without app store review delays.
