Unexpected Behavior in Midtrans BSI VA Transaction Response

[rmdhfz]

Dear Midtrans Team,

I have identified an issue related to the payment response for Bank BSI.
In the callback response, the order_id and transaction_id returned are exactly the same, whereas they should be different values.

"notifications": {
    "status_code": "200",
    "transaction_id": "A120251205074834XeVg4mKHIMID",
    "gross_amount": "113500.00",
    "currency": "IDR",
    "order_id": "A120251205074834XeVg4mKHIMID",
    "payment_type": "bank_transfer",
    "signature_key": "5c0984408570a5dfcfd15ba42e46e552f41750a46ebcf0203fe72d01801c7eadc14e59c34c1227b04d50503de0426ea79027bbd55fd1d03f6f4382010520bfac",
    "transaction_status": "settlement",

            "va_number": "20203314732052930"
        }
    ],
    "payment_amounts": [],
    "transaction_time": "2025-12-05 14:48:34",

},

    "transaction_status": "settlement",
    "fraud_status": "accept",
    "status_message": "Success, transaction is found",
    "merchant_id": "G681706693",
    "va_numbers": [
        {
            "bank": "bsi",
            "va_number": "20203314732052930"
        }
    ],
    "payment_amounts": [],
    "transaction_time": "2025-12-05 14:48:34",
    "settlement_time": "2025-12-05 14:49:38",
    "expiry_time": "2025-12-06 14:48:34"
}

The notification object is obtained from:

$notif                  = new \Midtrans\Notification();
$response           = (object) $notif->getResponse();

The status object is obtained from:
$status = \Midtrans\Transaction::status($transaction_id);

Could you please verify and clarify why both IDs are identical, and confirm whether this is expected behavior specifically for BSI transactions?

Thank you for your assistance.
