Telegram Mini App

Integrate QuantaPay payments into Telegram Mini Apps for seamless in-chat commerce.

Overview

Telegram Mini Apps (formerly Web Apps) are web-based applications that run inside the Telegram messenger. By integrating QuantaPay, you can accept cryptocurrency payments directly within Telegram.

Integration Approach

Use the QuantaPay Checkout Session API to create payments from your Mini App:

1. Your backend calls create-checkout-session to create a payment.
2. Open the payment_url in the Telegram WebView or redirect the user.
3. The customer pays on the QuantaPay payment page.
4. Your backend receives a webhook when payment is confirmed.

Example Flow

// In your Mini App frontend
async function handlePayment(amount, currency) {
  // Call your backend to create a checkout session
  const response = await fetch('/api/create-payment', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ amount, currency })
  });

  const { payment_url } = await response.json();

  // Open payment URL in Telegram
  window.Telegram.WebApp.openLink(payment_url);
}

// Your backend endpoint
$result = file_get_contents('https://cloud.quantapay.app/api.php', false,
  stream_context_create([
    'http' => [
      'method' => 'POST',
      'header' => 'Content-Type: application/x-www-form-urlencoded',
      'content' => http_build_query([
        'function' => 'create-checkout-session',
        'api-key' => 'YOUR_API_KEY',
        'price' => $_POST['amount'],
        'currency' => $_POST['currency'],
        'redirect' => 'https://t.me/YourBot/app', // Return to Mini App
      ])
    ]
  ])
);
