What is WebView
WebView is a technology that enables web content to be displayed directly inside a mobile or desktop application. It functions as an embedded browser, but the user remains within the app’s interface without switching to an external browser.
WebView is a widely used solution across many major platforms:
- Facebook and Instagram open links within the app using WebView.
- TikTok embeds forms, ads, and mini apps via WebView.
- Banking apps display contracts, product catalogs, or secure login screens.
- Marketplaces and aggregators open partner pages or delivery terms without leaving the app.
In all these cases, this approach allows developers to integrate web-based interfaces into apps, maintaining control over the user experience without redirecting users outside the platform.
Advantages
- Preserves a unified app interface — no need to open an external browser.
- Works across devices and platforms.
- Requires no installation — everything loads online.
- Gives developers control over layout and logic of displayed content.
WebView in Telegram
In Telegram, WebView is used to launch Web Apps — web-based applications embedded within the messenger. When a user clicks a button in a bot, a window opens to load the web app directly from the developer’s server. This window functions as an embedded browser window.
With WebView, you can
- Run Web Apps inside Telegram without switching to a browser
- Maintain user authentication and pass session data
- Connect the Web App to a bot via the Telegram Web App API, enabling data exchange and interaction
- Accept payments using Telegram Payments
- Control the appearance and behavior of the application within Telegram
- Provide a fast, seamless user experience inside the messenger.
Examples of in-app browser use in Telegram
- Games and quizzes launched in chats
- Application forms or registration flows inside bots
- Product catalogs and shopping carts
- Interactive learning modules
- Any other Web Apps triggered via button click.
WebView and Telegram Ads
In Telegram Ads, users — after clicking on an ad — are sent directly into a full-featured Web App such as a store, game, form, or survey. This reduces friction, shortens the path to action, and increases conversion rates.
WebView is a key tool for launching digital products inside Telegram. It ensures fast, visually consistent, and technically flexible interaction — without requiring separate app installs or browser redirections.
