First Mini App Tutorial

With the skills and tools in place, you’re ready to build your first Mini App using Telegram’s platform features:

1. Set Up Your Bot
   Use BotFather to create a new bot and get your API credentials. Install the required tools and choose a framework (Telegram recommends the official React template) [6][7].
2. Develop Your Interface
   Build your web app using JavaScript and HTML5. Prioritize mobile-first design and ensure the interface matches Telegram’s style.

Development Guidelines

Creating effective Telegram Mini Apps requires adhering to key design principles and best practices to deliver a smooth user experience across various devices and platforms.

Mobile Design Tips

Designing for mobile? Focus on these key elements:

On Android, tailor animation complexity using the User-Agent string to maintain smooth performance.

Once you’ve got the interface down, take advantage of Telegram’s built-in features to elevate your app.

Telegram Features Guide

After optimizing your design, integrate Telegram’s native features for a better user experience. Here’s how to do it:

1. Launch Methods Integration

Mini Apps can be launched through various entry points, such as profile buttons, keyboard buttons, and inline modes. Use these methods to handle data:

• Use Telegram.WebApp.sendData for keyboard button-triggered launches.
• Implement answerWebAppQuery for inline button interactions.
• Configure menu buttons with BotFather or the setChatMenuButton method.

2. User Data Handling

Securely access user information via the WebAppUser class. If users allow it, you can retrieve profile photos using the photo_url field to personalize their experience.

3. Chat Context Management

Use chat_type and chat_instance parameters to track chat context when users open your Mini App through direct links. This ensures consistent functionality across different chat environments.

Testing Methods

Testing is critical. Use these methods to debug your app across platforms:

For universal debugging, add the Eruda console to your development setup. Also, test your app under real-world conditions across different device performance levels. On Android, performance data is easily accessible via the User-Agent string.

Making Money with Mini Apps

You can earn revenue from your Telegram Mini App through direct payments, ads, and cryptocurrency options.

Setting Up Payments

Telegram’s Bot Payments API allows secure transactions without charging a commission. Here’s a breakdown of its features:

To get started, create a bot via BotFather and use the sendInvoice method. Test your setup with Stripe’s TEST MODE before launching. Beyond direct payments, consider other revenue options to expand your earning potential.

Ad Integration

Advertising is another way to generate income. Platforms partnered with FindMini.app help developers monetize effectively. These platforms offer:

• Flexible targeting options
• Multiple ad formats
• Performance analytics
• Low minimum payout thresholds (as little as $1)
• Regular payment schedules

This makes ads a reliable and scalable revenue stream.

TON Payments

The TON Blockchain integration enables cryptocurrency payments through Telegram Stars. Here’s how it works:

• In-App Purchases: Apps like Catizen let users top up balances using Telegram Stars, generating significant earnings (over $5 million)[8].
• Asset Exchange: Users can swap Telegram Stars for Toncoin via Fragment, offering more payment flexibility.
• Revenue Sharing: Apps like Major and PAWS utilize Telegram Stars and Toncoin for effective revenue-sharing models.

Tim Wong, Chairman of the Catizen Foundation, notes:

“TON’s robust technical foundation and thriving developer community are driving our expansion.”[8]

Using a mix of these monetization methods can maximize your app’s earnings. Leverage FindMini.app’s analytics tools to monitor user behavior and refine your strategy for better results.
