v3 退款接口文档

https://pay.weixin.qq.com/wiki/doc/api/wxpay/ch/fusion_wallet_ch/MiniProgramPay/chapter8_2.shtml#top


参数传的都没用问题

{
    "appid": "wx6d******82",
    "mchid": "1******3261",
    "transaction_id": "42000******724",
    "out_trade_no": "000009",
    "out_refund_no": "aaaaaaaaa",
    "amount": {
        "refund": 1,
        "total": 2,
        "currency": "CNY"
    },
    "reason": "退款测试",
    "notify_url": "https://3da873dd3c62.******/api/or"
}

就是报 参数错误


{
    "code": "PARAM_ERROR",
    "message": "参数格式错误",
    "detail": {
        "field": "#",
        "issue": "缺少必填字段",
        "location": "body"
    }
}
