# 4.1 API Reference - Click Verification

## Click Verification

The **Apps Network** system supports task click verification and ensures accurate tracking and rewarding of user engagement.

### API Endpoint

For your TMA, use the following API endpoint:

```
GET https://click.dmtp.tech/banners/verify?tui=
```

### Parameters

* `tui`: Telegram User ID (only for TMA environments)

#### Usage

Retrieve the Telegram User ID from the TMA environment and use it in the API call:

```
GET https://click.dmtp.tech/banners/verify?tui=123456789
```

#### JavaScript Example (TMA)

```javascript
// Assuming you're using the Telegram WebApp API
const tui = window.Telegram.WebApp.initDataUnsafe.user.id;

if (tui) {
    fetch(`https://click.dmtp.tech/banners/verify?tui=${encodeURIComponent(tui)}`)
        .then(response => response.json())
        .then(data => {
            if (data.valid) {
                console.log('Valid click! Reward the user.');
                // Add your reward logic here
            }
        })
        .catch(error => console.error('Error:', error));
}
```

### Implementation Notes

1. In TMA mode, prioritize using the Telegram User ID for verification.
2. The click verification data is cached for 5 minutes. Perform the verification promptly after the user enters your game.
3. If the verification is successful, award the user with the predetermined in-game bonus.

By correctly implementing this click verification system, you ensure that users are properly rewarded for engaging with tasks, maintaining the integrity of the advertising ecosystem.
