Quick setup

0. Host the Web App in GitHub Pages

The Web App must be hosted somewhere. Hosting it on a GitHub repository is a quick, free way to do it:

  1. Create a repository (or fork this one)
  2. On the repository: Settings > Pages:
    • Source: Deploy from a branch
    • Branch: master, / (root), Save
  3. Wait a few minutes for the web to be deployed. It will be available at: https://{github-username}.github.io/{repository-name}/{location-inside-repository}. In this case: https://revenkroz.github.io/telegram-web-app-bot-example/index.html

1. Show the user a button to open a Web App. There are two ways:

  1. Show the user a special menu button (near the message input field):

    1. Go to Bot Father
    2. Select your bot
    3. Bot Settings — Menu Button — Specify../Edit menu button URL
    4. Send a URL to your Web App (in this case, https://revenkroz.github.io/telegram-web-app-bot-example/index.html)

  2. The second way is to send a button with the data that contains field web_app with a URL to a Web App:

    {
    "text": "Test web_app",
    "web_app": {
        "url": "https://revenkroz.github.io/telegram-web-app-bot-example/index.html"
    }
}

2. Add script to your Web App

To connect a Web App to the Telegram client, place the script telegram-web-app.js in the <head> tag before any other scripts, using this code (more info):

<script src="https://telegram.org/js/telegram-web-app.js"></script>

Once the script is connected, a window.Telegram.WebApp object will become available.

3. Do the thing.
