Yukassa, creating a payment for an order without goods?

Question

API

Good day.
At the moment, the default payment module generates a request to create a payment indicating the items array, something like this comes out.

{
  "amount": {
    "value": "4000.00",
    "currency": "RUB"
  },
  "confirmation": {
    "type": "redirect",
    "return_url": "https://site/order/success/?invoice_id=17014"
  },
  "capture": true,
  "description": "Оплата заказа 30462",
  "metadata": {
    "invoice_id": "11111",
    "signature": "74792c111ab1a7b1911cb1ed00174bb4b33cb9b2a"
  },
  "receipt": {
    "tax_system_code": 1,
    "customer": {
      "full_name": "***",
      "email": "[email protected]",
      "phone": "***"
    },
    "items": [
      {
        "description": "Товар 1 ",
        "quantity": "1.000",
        "amount": {
          "value": "4000.00",
          "currency": "RUB"
        },
        "vat_code": "2",
        "payment_subject": "full_prepayment",
        "payment_mode": "advance"
      }
    ]
  }
}

The essence of the fact that the task needs to print an advance check, i.e. the payment_mode parameter must be advance, and the attribute of the settlement subject must be "payment", not "goods", because We will not report for the goods, but for the entire order.
I don't understand how to build the query then.
