TL;DR

A web app that opens inside Telegram, so you get a real interface — like an inbox — without leaving the messaging app.

Key Points

✓

Mini Apps are ordinary web pages (HTML, CSS, JavaScript) opened by a [[telegram-bot]] inside Telegram's in-app browser [1].

✓

Telegram injects a JavaScript bridge that exposes theme colors, viewport controls, and the launching user's identity [1].

✓

Launch data is signed by Telegram, so your server can verify who opened the app rather than trusting the client [1].

✓

For support, a Mini App gives operators a real inbox — threading and history that plain chat replies cannot offer.

✓

They inherit Telegram's theme, so a well-built Mini App looks native in both light and dark mode.

✓

Compared with a [[javascript-widget]] on your own site, the Mini App is the operator-side surface, not the visitor-side one.

What a Mini App is

A Telegram Mini App is simply a website that Telegram agrees to open inside itself ^[1]. A Telegram Bot offers a button; tapping it opens your URL in an in-app browser view sized to the chat. Because it is standard web technology, you build it with whatever stack you already use — there is no separate SDK language or app-store review. What makes it more than an embedded browser tab is the bridge Telegram injects: your page can read the user's color theme, expand or collapse the viewport, show Telegram's own main button, and close itself when finished. The result feels like part of the app rather than a link that threw the user out into Safari.

Verifying who opened it

When Telegram launches a Mini App it passes initialization data describing the user, and that payload is cryptographically signed with a hash derived from your bot token ^[1]. Your server recomputes the hash to confirm the data genuinely came from Telegram and was not forged by someone opening the URL directly. This matters because it is what lets a Mini App act as an authenticated surface — the operator does not log in with a password; their Telegram identity is the login. For a support inbox that is a meaningful simplification, since it removes an entire account system and, with it, the Visitor Identification and credential-handling problems that come with one.

Why it complements reply-to-message

Answering a forwarded Chat Message by replying to it in Telegram is fast, but it is a thin interface: no history, no list of open threads, no way to see which Conversation is still waiting. A Mini App inbox fills that gap. The operator opens it from the bot and gets a genuine list view — conversations, message history, visitor context such as page URL and IP Geolocation — while still never leaving Telegram. In practice the two work together: quick answers happen by reply-to-message from the notification, and anything needing context happens in the Mini App. That pairing is what makes Telegram Customer Support viable beyond a handful of messages a day.

Telegram Bot

A Telegram bot is an automated account inside Telegram, run by software rather than a person, that can send and receive messages through the Telegram Bot API. Businesses use bots to deliver website chat messages, notifications, and support conversations into Telegram, where they can be answered from a phone.

Telegram Integration

Telegram Integration is the mechanism by which Eloqra routes every website chat into the project owner's Telegram, forwarding visitor messages to a Telegram bot and flowing operator replies back to the widget. It turns Telegram into the operator inbox, so there is no separate agent console you are required to keep open.

Telegram Customer Support

Telegram customer support is the practice of handling customer questions through Telegram instead of a traditional help desk — either by talking to customers in Telegram directly, or by routing website chat into Telegram so the business can reply from the app it already uses.

JavaScript Widget

A JavaScript widget is a self-contained chunk of front-end code, loaded from a single script tag, that injects an interactive UI into any third-party web page. In Eloqra it is the live-chat widget that boots from one snippet and renders the chat launcher and conversation panel directly on a customer's site.

Conversation

A conversation is the threaded exchange of messages between a single website visitor and a project's operators, grouped as one unit with a status and unread counters. In Eloqra it is the container that holds every message, the visitor's captured context, and the assigned operator.

Shared Inbox

A shared inbox is a single collaborative workspace where multiple support team members can view, claim, and reply to incoming customer messages from one address or channel, while each person signs in with their own account. It replaces a password-shared mailbox so a whole team can answer customers without stepping on each other.
