普通服务商 -- 开通 “平台收付通”产品后，就不能在“合作伙伴功能--商户基础服务--商户资料填写”中，给商户进件了吗？只能使用特约商户给进件？

官方要求4.1前接入虚拟支付，那我有几个疑问，希望官方解答一下。 1 小程序开通虚拟支付时候，开通收款商户号，若是后面需要更换收款商户号，支持更换么？ 2 技术服务费的结算规则是什么？是用户付款后实时扣除，还是说订单状态发货后才扣除，或者说是固定周期结算？ 3 什么状态下可以退款？虚拟发货有没有自动确认收款的？——担心无法退款导致客诉。

请教一下，支付分订单能否正常参与分账处理

您好，我是小程序商户，我们现在想申请开通小额发放佣金功能，

请问我们需要通过微信支付v3的api，生成签约的二维码，让用户使用微信扫码签约，应该使用什么接口

大佬们，我想问一下，现在微信支付-付款码支付，也就是说用户出示微信付款码，商家通过扫描枪方式支付，这种支付方式的开发文档是用的v2接口吗？ 现在是不支持v3的对吧？我看文档上写的是，现在还在沿用v2的接口

我现在做的功能是微信商家转账到个人微信，然后用证书的方式验签，因为之后还有充值 现在开通的是平台证书，然后这是我的请求代码：// ========== 内部请求方法 ========== private static TransferResponse doRequest(TransferRequest request) { String uri = "/v3/fund-app/mch-transfer/transfer-bills"; String reqBody = new Gson().toJson(request); Request.Builder builder = new Request.Builder() .url(HOST + uri) .addHeader("Accept", "application/json") .addHeader("Wechatpay-Serial", WECHAT_PAY_PUBLIC_KEY_ID) .addHeader("Authorization", WXPayUtility.buildAuthorization( MCHID, CERT_SERIAL_NO, PRIVATE_KEY, "POST", uri, reqBody)) .addHeader("Content-Type", "application/json") .post(RequestBody.create(reqBody, JSON)); Request httpRequest = builder.build(); try (Response response = HTTP_CLIENT.newCall(httpRequest).execute()) { String respBody = WXPayUtility.extractBody(response); if (response.code() >= 200 && response.code() < 300) { // 2XX 成功，验证应答签名 WXPayUtility.validateResponse(WECHAT_PAY_PUBLIC_KEY_ID,WECHAT_PAY_PUBLIC_KEY, response.headers(), respBody); return WXPayUtility.fromJson(respBody, TransferResponse.class); } else { throw new WXPayUtility.ApiException(response.code(), respBody, response.headers()); } } catch (IOException e) { throw new RuntimeException("网络请求失败", e); } 现在是String respBody = WXPayUtility.extractBody(response);这里能正常返回，返回的是需要用户确认收款，看着数据是正常的，但是走到// 2XX 成功，验证应答签名 WXPayUtility.validateResponse(WECHAT_PAY_PUBLIC_KEY_ID,WECHAT_PAY_PUBLIC_KEY, response.headers(), respBody);这里的时候就报错了，Validate response failed,the WechatPay signature is incorrect. 下面是打印出来的信息： Validate response failed,the WechatPay signature is incorrect.
