### Generate Payment Signature in Python

Source: https://docs.mixplat.ru/extensions

This Python snippet shows how to create the MD5 signature for a low-level payment initiation. It uses the `hashlib` module and requires the API key, project ID, request ID, and merchant payment ID.

```Python
import hashlib
api_key = '6yh9ik3f1734f29e3dc0118034277e67504rfjj9'
project_id = 123456
request_id = 'test_request_id'
merchant_payment_id = 'test_merchant_payment_id'
signature_string = f"{request_id}{project_id}{merchant_payment_id}{api_key}"
signature = hashlib.md5(signature_string.encode()).hexdigest()

```

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

### Handle Payment Process Initialization

Source: https://docs.mixplat.ru/widget-options

Use setProcessCallback to execute a function when the payment process begins. This callback is intended for lightweight actions as the payment is initializing.

```javascript
M.setProcessCallback(function(o, i){
    // действия в момент начала обработки платежа 
    console.log('pending');
});
```

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