为了在保证支付安全的前提下,带给商户简单、一致且易用的开发体验,我们推出了全新的微信支付APIv3接口。该版本API的具体规则请参考“APIv3接口规则”
为了帮助开发者调用开放接口,我们提供了JAVA、PHP、GO三种语言版本的开发库,封装了签名生成、签名验证、敏感信息加/解密、媒体文件上传等基础功能(更多语言版本的开发库将在近期陆续提供)
测试步骤:
1、根据自身开发语言,选择对应的开发库并构建项目,具体配置请参考下面链接的详细说明:
• wechatpay-java(推荐)wechatpay-apache-httpclient,适用于Java开发者。
• wechatpay-php(推荐)、wechatpay-guzzle-middleware,适用于PHP开发者
注:当前开发指引接口PHP示例代码采用wechatpay-guzzle-middleware版本
• wechatpay-go,适用于Go开发者
更多资源可前往微信支付开发者社区搜索查看
2、创建加载商户私钥、加载平台证书、初始化httpClient的通用方法
@Before
public void setup() throws IOException {
// 加载商户私钥(privateKey:私钥字符串)
PrivateKey merchantPrivateKey = PemUtil
.loadPrivateKey(new ByteArrayInputStream(privateKey.getBytes("utf-8")));
// 加载平台证书(mchId:商户号,mchSerialNo:商户证书序列号,apiV3Key:V3密钥)
AutoUpdateCertificatesVerifier verifier = new AutoUpdateCertificatesVerifier(
new WechatPay2Credentials(mchId, new PrivateKeySigner(mchSerialNo, merchantPrivateKey)),apiV3Key.getBytes("utf-8"));
// 初始化httpClient
httpClient = WechatPayHttpClientBuilder.create()
.withMerchant(mchId, mchSerialNo, merchantPrivateKey)
.withValidator(new WechatPay2Validator(verifier)).build();
}
@After
public void after() throws IOException {
httpClient.close();
}
3、基于接口的示例代码,替换请求参数后可发起测试
说明:
• 上面的开发库为微信支付官方开发库,其它没有审核或者控制下的第三方工具和库,微信支付不保证它们的安全性和可靠性
通过包管理工具引入SDK后,可根据下面每个接口的示例代码替换相关参数后进行快速测试
• 开发者如果想详细了解签名生成、签名验证、敏感信息加/解密、媒体文件上传等常用方法的具体代码实现,可阅读下面的详细说明:
1.签名生成
2.签名验证
3.敏感信息加解密
• 如想更详细的了解我们的接口规则,可查看我们的接口规则指引文档
服务商可登录【服务商平台-合作工具箱】申请开通【连锁品牌工具箱】。进行品牌申请、查看品牌申请进度、邀请品牌总部授权、品牌门店管理、品牌流量场景管理等日常管理。
连锁工具箱开通后,品牌主在商户平台进入:“品牌专区-品牌交易-品牌供应链分账-供应链分账管理”中可进行分账比例的调整。
步骤4 分账前需调用《添加分账接收方》接口添加分账接收方。
步骤6 分账订单发起分账需调用《请求分账》接口进行分账,微信支付将会把结算资金分给分账接收方。
步骤8 分账完成后,微信会通过《分账动账通知》接口,主动通知商户。商户也可以通过《查询分账结果》接口,主动查询分账结果。
步骤12分账后若产生退款,则需先调用《请求分账回退》接口,请求将已经分给分账方的资金回退,再处理退款。
步骤13分账回退完成后,微信同样会通过《分账动账通知》接口,主动通知商户。商户也可以通过《查询分账回退结果》接口,主动查询分账结果。
步骤17分账结束后,商户需调用《完结分账》接口结束分账订单。
文档展示了如何使用微信支付服务端 SDK 快速接入连锁品牌分账产品,完成与微信支付对接的部分。
注意:
步骤说明:微信订单支付成功后,由服务商发起分账请求,将结算后的资金分给分账接收方。

A:请按照以下几点检查:
1. 微信订单号填写错误
2. 下单的时候未传分账标识(profit_sharing)的订单,是没有分账权限的
A:请按照以下几点检查:
1. 该订单已全额退款,没有资金可以分账
2. 已经调用过“请求单次分账”,订单剩余的待分账金额已经解冻,已无分账资金
2. 超过订单可分账金额或者该订单已无可分账金额,请检查确认
A:请按照以下几点检查:
1. 请在订单支付成功1分钟后再调用分账接口
2. 未结算的订单,请在结算后再调用分账接口请求分账
3. 老资金流商户的订单,不支持分账
4. 商户开通了收支分离但手续费账户余额不足(手续费账户最低余额要求是100元以上,在充值手续费账户1小时后,订单会正常结算,即可正常调用分账接口)
A:请按照以下几点检查:
1. 分账接收商户全称填写错误,请填写正确的商户全称
2. 接口需要使用UTF-8编码
A:receiver中的参数account错误,参数account的规则如下:
1. 类型是MERCHANT_ID时,是商户ID
2. 类型是PERSONAL_OPENID时,是个人openid
3. 类型是PERSONAL_SUB_OPENID时,是个人sub_openid
4. APPID与mchid不匹配也会报该错误,请检查确认
5. 签名类型错误,分账接口签名类型目前只支持HMAC-SHA256
