商家券开发指引

1. 接口规则

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”
备注：当前接口用于微信国内钱包

2. 开发准备

2.1. 搭建和配置开发环境

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

2、创建加载商户私钥、加载平台证书、初始化httpClient的通用方法

JAVA
PHP


@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();
}


use GuzzleHttp\Exception\RequestException;
use WechatPay\GuzzleMiddleware\WechatPayMiddleware;
use WechatPay\GuzzleMiddleware\Util\PemUtil;
use GuzzleHttp\HandlerStack;
 
// 商户相关配置，
$merchantId = '1000100'; // 商户号
$merchantSerialNumber = 'XXXXXXXXXX'; // 商户API证书序列号
$merchantPrivateKey = PemUtil::loadPrivateKey('./path/to/mch/private/key.pem'); // 商户私钥文件路径
 
// 微信支付平台配置
$wechatpayCertificate = PemUtil::loadCertificate('./path/to/wechatpay/cert.pem'); // 微信支付平台证书文件路径
 
// 构造一个WechatPayMiddleware
$wechatpayMiddleware = WechatPayMiddleware::builder()
    ->withMerchant($merchantId, $merchantSerialNumber, $merchantPrivateKey) // 传入商户相关配置
    ->withWechatPay([ $wechatpayCertificate ]) // 可传入多个微信支付平台证书，参数类型为array
    ->build();
 
// 将WechatPayMiddleware添加到Guzzle的HandlerStack中
$stack = GuzzleHttp\HandlerStack::create();
$stack->push($wechatpayMiddleware, 'wechatpay');
 
// 创建Guzzle HTTP Client时，将HandlerStack传入，接下来，正常使用Guzzle发起API请求，WechatPayMiddleware会自动地处理签名和验签
$client = new GuzzleHttp\Client(['handler' => $stack]);


/*
    Package core 微信支付api v3 go http-client 基础库，你可以使用它来创建一个client，并向微信支付发送http请求
    只需要你在初始化客户端的时候，传递credential以及validator
    credential用来生成http header中的authorization信息
    validator则用来校验回包是否被篡改
    如果http请求返回的err为nil，一般response.Body 都不为空，你可以尝试对其进行序列化
    请注意及时关闭response.Body
    注意：使用微信支付apiv3 go库需要引入相关的包，该示例代码必须引入的包名有以下信息

    "context"
    "crypto/x509"
    "fmt"
    "io/ioutil"
    "log"
    "github.com/wechatpay-apiv3/wechatpay-go/core"
    "github.com/wechatpay-apiv3/wechatpay-go/core/option"
    "github.com/wechatpay-apiv3/wechatpay-go/utils"

    */
func SetUp() (opt []option.ClientOption, err error) {
    //商户号
    mchID := ""
    //商户证书序列号
    mchCertSerialNumber := ""
    //商户私钥文件路径
    privateKeyPath := ""
    //平台证书文件路径
    wechatCertificatePath := ""

    // 加载商户私钥
    privateKey, err := utils.LoadPrivateKeyWithPath(privateKeyPath)
    if err != nil {
        log.Printf("load private err:%s", err.Error())
        return nil, err
    }
    // 加载微信支付平台证书
    wechatPayCertificate, err := utils.LoadCertificateWithPath(wechatCertificatePath)
    if err != nil {
        log.Printf("load certificate err:%s",err)
        return nil, err
    }
    //设置header头中authorization信息
    opts := []option.ClientOption{
        option.WithMerchant(mchID, mchCertSerialNumber, privateKey), // 设置商户相关配置
        option.WithWechatPay([]*x509.Certificate{wechatPayCertificate}), // 设置微信支付平台证书，用于校验回包信息用
    }
    return opts, nil
}

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

4.merchantPrivateKey（私钥）

5.wechatpayCertificates（平台证书）

6.APIV3Key（V3 key）

• 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

2.2. 业务开发配置

2.2.1. 开通营销事件推送能力

• 开通营销事件推送能力说明：

a. 用于设置接收商家券相关事件通知的URL，可接收商家券相关的事件通知、包括发放通知等。需要设置接收通知的URL，并在商户平台开通营销事件推送的能力，即可接收到相关通知。

b. 营销事件推送：点击开通产品权限。由商家券批次创建方登录Pay平台，操作开通

3. 快速接入

3.1. 业务流程图

业务流程时序图：

重点步骤说明：

步骤1 商户发起创建商家券请求，可通过《创建商家券》接口创建商家券，微信支付生成商家券批次后并返回商家券批次号给到商户。
请求参数商户logo（merchant_url）的内容要求使用图片上传（营销专用）接口上传后获取

步骤4.2 商户获取到商家券批次号，需要调用《小程序发券插件》来发放商户券，并获取微信支付返回商家券发放结果。

步骤7.2 商户发券成功后，商户可通过《查询商家券详情》、《根据过滤条件查询用户券》、《查询用户券详情》等商家券管理接口进行券管理，商户需核销用户券时，可通过调用《核销用户券》来核销用户微信卡包中具体某一张商家券。

3.2. API接入（含示例代码）

文档展示了如何使用微信支付服务端 SDK 快速接入商家券产品，完成与微信支付对接的部分。

注意：

文档中的代码示例是用来阐述 API 基本使用方法，代码中的示例参数需替换成商户自己账号及请求参数才能跑通。
以下接入步骤仅提供参考，请商户结合自身业务需求进行评估、修改。

3.2.1. 【服务端】创建商家券

步骤说明：通过此接口可为有需求的商户创建商家券。当前支持创建的商家券类型包含满减券、换购券和折扣券三种。

重要入参说明：

• belong_merchant：批次归属商户号，批次归属于哪个商户。直连商户请填写直连商户号

• out_request_no：商户请求单号，商户创建批次凭据号（格式：商户id+日期+流水号），商户侧需保持唯一性。

• max_coupons：批次最大发放个数，批次最大可发放个数限制。特殊规则：取值范围 1 ≤ value ≤ 1000000000

• notify_appid：事件通知appid，用于回调通知时，计算返回操作用户的openid（诸如领券用户），支持小程序or公众号的APPID；如该字段不填写，则回调通知中涉及到用户身份信息的openid与unionid都将为空。

注意：

更多参数、响应详情及错误码请参见创建商家券接口文档

3.2.2. 【服务端】查询商家券详情

步骤说明：商户可通过该接口查询已创建的商家券批次详情信息。

3.2.17.【服务端】领券事件回调通知

步骤说明：领券完成后，微信会把相关领券结果和用户信息发送给商户，商户需要接收处理，并按照文档规范返回应答。出于安全的考虑，我们对支付结果数据进行了加密，商户需要先对通知数据进行解密，才能得到支付结果数据。

注意：

领券事件通知是以POST 方法访问商户设置的通知url，通知的数据以JSON 格式通过请求主体（BODY）传输。通知的数据包括了加密的支付结果详情
加密不能保证通知请求来自微信。微信会对发送给商户的通知进行签名，并将签名值放在通知的HTTP头Wechatpay-Signature。商户应当验证签名，以确认请求来自微信，而不是其他的第三方。签名验证的算法请参考《微信支付API v3签名验证》。
支付通知http应答码为200或204才会当作正常接收，当回调处理异常时，应答的HTTP状态码应为500，或者4xx
商户成功接收到回调通知后应返回成功的http应答码为200或204
同样的通知可能会多次发送给商户系统。商户系统必须能够正确处理重复的通知。推荐的做法是，当商户系统收到通知进行处理时，先检查对应业务数据的状态，并判断该通知是否已经处理。如果未处理，则再进行处理；如果已处理，则直接返回结果成功。在对业务数据进行状态检查和处理之前，要采用数据锁进行并发控制，以避免函数重入造成的数据混乱
对后台通知交互时，如果微信收到应答不是成功或超时，微信认为通知失败，微信会通过一定的策略定期重新发起通知，尽可能提高通知的成功率，但微信不保证通知最终能成功。（通知频率为60s/次 - 总计11次）

4. 常见问题

Q：调用创建商家券接口返回“非法敏感图片”

A：请求参数商户logo（merchant_url）的内容要求使用图片上传（营销专用）接口上传后获取，请检查确认。

Q：创建商家券接口，goods_name字段展示在哪里？

A：展示在商家券详情里面的优惠说明中

Q：调用修改商家券基本信息API返回：无法将输入源“/body/stock_id”映射到目标字段“批次号”中，此字段并非多重字段但被输入源“/uri_template/stock_id”映射过了

A：请注意参数stock_id传到请求url里面，body里面就不用传该参数

Q：商家券领券回调，正常设置地址，为什么接收不到回调信息？

A：请按以下几点检查

1. 请检查是否有正确设置apiv3。设置步骤如下：【微信商户平台—>账户设置—>API安全—>设置apiv3】

2. 请检查回调url是否能正常公网访问

3. 如果是http地址，建议更换支持https

4. 是否开启了防火墙，如果开户了防火墙，请添加微信支付营销回调IP：
