平台型服务商会有多个小程序和商户平台,用户再不同的小程序付款成功后,申请退款需要从相对应的商户平台来退款,在退款回调通知我这边的时候我需要怎样来匹配appid和商户号呢?
微信支付退款,多个商户时,如果根据不同商户来匹配退款回调通知?WeChat payment refund, when there are multiple merchants, if the refund callback notification is matched according to different merchants?

The platform service chamber of Commerce has multiple applets and merchant platforms. After users successfully pay for different applets, they need to refund from the corresponding merchant platform. When the refund callback notifies me, how do I match the appid and merchant number?
回答:
subopenid考虑看看
订单号查下?
1、每个小程序配置通知地址不要设置一个
2、通过回调的Wechatpay-Serial来匹配
