如何使授权交易Shopify无效

Question

我正在尝试向此交易发送无效种类：

{
    "transactions": [
        {
            "id": xxxxxx,
            "order_id": yyyyyy,
            "kind": "authorization",
            "gateway": "mercado_pago",
            "status": "success",
            "message": null,
            "created_at": "2019-10-09T09:00:08-04:00",
            "test": false,
            "authorization": null,
            "location_id": null,
            "user_id": null,
            "parent_id": null,
            "processed_at": "2019-10-09T09:00:08-04:00",
            "device_id": null,
            "receipt": {},
            "error_code": null,
            "source_name": "xxxxxx",
            "amount": "300.00",
            "currency": "BRL",
            "admin_graphql_api_id": "gid://shopify/OrderTransaction/xxxxxx"
        }
    ]
}

我现在的无效格式请求：（我尝试更改所有可能的参数，但一直说它不是 “要求parent_id引用可作废/可退款的交易”）

请求：

{
    "transaction": {
        "parent_id": xxxxxx, // < same id of the previous transaction
        "gateway": "mercado_pago",
        "kind": "void"
    }
}

响应：

{
    "errors": {
        "transactions": [
            "require a parent_id referring to a voidable/refundable transaction"
        ]
    }
} 

我真的不知道如何通过API取消此授权。

预先感谢
