开发指引

更新时间：2024.11.15

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。

2. 开发准备

2.1. 搭建和配置开发环境

开发者应当依据自身的编程语言来构建并配置相应的开发环境。

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2 创建代金券：商户可通过《创建代金券批次》接口创建代金券，微信支付生成代金券批次后并返回代金券批次号给到商户。

步骤7 激活代金券：商户获取到代金券批次号，需要确认并激活代金券，该批次代金券才能发放，需要调用《激活代金券批次》接口来激活创建的代金券。

步骤12 发放代金券：已经激活的代金券，商户可调用微信支付《发放指定批次的代金券》接口来进行代金券发放，并获取微信支付返回代金券发放结果。

步骤17 管理代金券：商户发券成功后，商户可通过《查询批次详情》、《查询代金券详情》等代金券管理接口进行券管理。

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 快速接入支付有礼，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】创建代金券批次

步骤说明：通过创建代金券批次接口，可创建代金券的类型包含预充值和免充值两种类型。

预充值代金券适用于第三方出资策划的活动，例如：满100减10. 指订单金额100元，用户实付90元，商户实收100元。
免充值适用于商户策划的活动，例如：满100减10。指订单金额100元，用户实付90元（用户领券后，在支付中直接核销10元），商户实收90元。

步骤说明：用于设置接收营销事件通知的URL，可接收营销相关的事件通知，包括核销、发放、退款等。

示例代码

JAVA

1public void SetCouponCallback() throws Exception{
2    //请求URL
3    HttpPost httpPost = new HttpPost("https://api.mch.weixin.qq.com/v3/marketing/favor/callbacks");
4    // 请求body参数
5    String reqdata = "{"
6            + "\"mchid\":\"9856888\","
7            + "\"notify_url\":\"https://pay.weixin.qq.com\""
8            + "}";
9    StringEntity entity = new StringEntity(reqdata,"utf-8");
10    entity.setContentType("application/json");
11    httpPost.setEntity(entity);
12    httpPost.setHeader("Accept", "application/json");
13    //完成签名并执行请求
14    CloseableHttpResponse response = httpClient.execute(httpPost);
15    try {
16        int statusCode = response.getStatusLine().getStatusCode();
17        if (statusCode == 200) { //处理成功
18            System.out.println("success,return body = " + EntityUtils.toString(response.getEntity()));
19        } else if (statusCode == 204) { //处理成功，无返回Body
20            System.out.println("success");
21        } else {
22            System.out.println("failed,resp code = " + statusCode+ ",return body = " + EntityUtils.toString(response.getEntity()));
23            throw new IOException("request failed");
24        }
25    } finally {
26        response.close();
27    }
28}

PHP

1try {
2    $resp = $client->request(
3        'POST',
4        'https://api.mch.weixin.qq.com/v3/marketing/favor/callbacks', //请求URL
5        [
6            // JSON请求体
7            'json' => [
8                "mchid" => "9856888", 
9                "notify_url" => "https://pay.weixin.qq.com",
10            ],
11            'headers' => [ 'Accept' => 'application/json' ]
12        ]
13    );
14    $statusCode = $resp->getStatusCode();
15    if ($statusCode == 200) { //处理成功
16        echo "success,return body = " . $resp->getBody()->getContents()."\n";
17    } else if ($statusCode == 204) { //处理成功，无返回Body
18        echo "success";
19    }
20} catch (RequestException $e) {
21    // 进行错误处理
22    echo $e->getMessage()."\n";
23    if ($e->hasResponse()) {
24        echo "failed,resp code = " . $e->getResponse()->getStatusCode() . " return body = " . $e->getResponse()->getBody() . "\n";
25    }
26    return;
27}

重要入参说明：

notify_url：必须为HTTPS协议。如果链接无法访问，商户将无法接收到微信通知。通知URL必须为直接可访问的URL，不能携带参数。示例: https://pay.wechatpay.cn

3.2.15. 【服务端】核销事件回调通知

步骤说明：用户使用券后，微信会把相关核销券信息发送给商户，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，我们对核销券信息数据进行了加密，商户需要先对通知数据进行解密，才能得到核销券信息数据。

注意

核销券信息通知是以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1min1次，总计9次）

4. 常见问题

Q：创建代金券接口报错：“你配置的信息需要开通特殊权限”

A：请按以下步骤进行排查

stock_name：最多可填写9个字
max_coupons_per_user：单天发放个数上限不能为0
coupon_amount：10<=coupon_amount<=100000
available_time_after_receive：可用时间：相对时间，按分钟设置，是否1min<=分钟范围<=1440min
transaction_minimum校验规则：
- 使用门槛-券面额>=0.01（门槛要大于面额）
- 0.1元<=门槛<=100000
stock_type：目前只支持NORMAL
out_request_no：校验规则：不可以重复
开始时间结束时间控制在90天内
不可使用的时间参数不可以传递

Q：创建代金券报错“批次预算等于批次面额乘以发券数”

A：请按以下步骤进行排查

max_amount需要等于coupon_amount（面额） * max_coupons（发放总上限）
核对最终请求数据，并查看是否存在遗漏数据，建议使用postman进行调试

Q：创建代金券报错“活动未开始或已结束”

A：活动时间不能大于90天，请检查available_begin_time、available_end_time参数设置是否符合要求。

Q：激活代金券API，如果大于1min或者更久还报错“系统繁忙”？

A：请检查单个可用商户号下正在运营的活动是否控制在500个以内，若超过500个活动可能导致新活动激活失败的情况。

Q：设置消息通知地址报错“系统繁忙”

A：请按以下步骤进行排查

请检查notify_url设置是否正确，notify_url必须为HTTPS
notify_url地址为一个可访问的地址
notify_url不能携带参数。示例：https://pay.wechatpay.cn/wxpay/pay.action
