This comprehensive example integrates the script, defines options, sets up callbacks for payment status, and renders the payment form. It demonstrates a full setup for accepting payments.

```html
<div id="payment-form"></div>
```

```javascript
<script type="text/javascript" src="https://payanyway.ru/assistant-builder"></script>
```

```javascript
<script type="text/javascript">
    let options = {
        account: 32691195,
        amount: 12.34,
        transactionId: '1234567890-abcdef'
    };

    let assistant = new Assistant.Builder();

    // платёж прошёл успешно
    assistant.setOnSuccessCallback(function(operationId, transactionId) {
        // здесь можно сделать что угодно – например,
        // перенаправить на другую страницу
        location.replace("https://domain.domain");
    });

    // платёж не прошёл
    assistant.setOnFailCallback(function(operationId, transactionId) {
        // действия по обработке ошибок
    });

    // платёж обрабатывается
    assistant.setOnInProgressCallback(function(operationId, transactionId) {
        // действия по обработке промежуточного статуса операции
    });

    assistant.build(options, 'payment-form');
</script>

```

--------------------------------

### Step Checks Request

Source: https://docs.moneta.ru/assistant/v1/step-checks

MONETA.Assistant sends verification requests to the provider's 'Check URL' using GET or POST. The response must be in XML format. Multiple requests may be sent per order.

```APIDOC
## Request Parameters

- **MNT_COMMAND** (string) - For data retrieval requests, this should be `STEP`.
- **MNT_ID** (string) - Provider identifier in the MONETA.RU system.
- **MNT_AMOUNT** (number) - Actual amount excluding MONETA.RU commission. Optional if not provided in the HTML form.
- **MNT_CURRENCY_CODE** (string) - ISO currency code. Optional.
- **MNT_TEST_MODE** (string) - `1` for test mode, `0` for real mode. Optional.
- **MNT_SIGNATURE** (string) - Request signature.
- **STEP** (string) - The name of the current parameter input step (e.g., `PRE`).
- **CUSTOMFIELD:** (string) - Data passed in the request for additional data retrieval. Parameters starting with `CUSTOMFIELD:` are considered custom fields.
```

```APIDOC
## Signature Generation (Request)

```
MNT_SIGNATURE = MD5(
  MNT_COMMAND + MNT_ID + MNT_AMOUNT + MNT_CURRENCY_CODE + MNT_TEST_MODE
  + INTEGRITY_CHECK_CODE)
```

- `MNT_AMOUNT` in the signature should have two decimal places.
- If `MNT_AMOUNT` is absent in the request, it is skipped during signature calculation (empty string).
- In test mode, `1` is used in the signature; otherwise, `0`.

**Note:** If the amount is not in the request:
```
MNT_SIGNATURE = MD5(
  MNT_COMMAND + MNT_ID + MNT_CURRENCY_CODE + MNT_TEST_MODE
  + INTEGRITY_CHECK_CODE)
```
The provider must form a string with their data and request fields, calculate MD5, and compare it with the `MNT_SIGNATURE` in the request.
```
