大部分情况都能正常调用退款，偶尔出现这种情况，然后过了一会又可以了

我们小程序的分账模式是服务商模式，请问这种支付订单可以使用新版订阅进行订单状态推送吗？

支付公钥已经申请成功了，并且从平台证书切换到公钥模式了，然后微信平台证书作废后，公钥入口不见了，是为什么呢 [图片]

我这里服务器网络首先，出和入都需要白名单操作，从服务器请求https://api.mch.weixin.qq.com 需要知道 https://api.mch.weixin.qq.com 的IP地址。

公众号认证完之后小程序还需要认证费用吗？

财付通免输卡号绑卡测试秘钥，文档中两个私钥（一个是java用的）一个公钥，怎么理解？这个公钥跟这两个私钥都能够匹配？https://pay.weixin.qq.com/wiki/doc/apiv3/download/%E8%B4%A2%E4%BB%98%E9%80%9A%E5%85%8D%E8%BE%93%E5%8D%A1%E5%8F%B7%E7%BB%91%E5%8D%A1%E6%B5%8B%E8%AF%95%E7%A7%98%E9%92%A5.pdf
