通知类型 notification_type=REFUND ，即消耗类内购商品退款， unified_receipt 存放着历史退款订单信息，我们可以循环处理每条退款内容，根据每条退款订单下的苹果订单编号 transaction_id 找到一一对应我们自身订单，记录好每一笔退款，查出详情，针对用户进行扣除资源扣除或封号。

简单一个php处理思路

$data = json_decode($appcb, true);

// 如果非消耗类退款
if ($data['notification_type'] != 'REFUND') {
    return;
}
// 如果非生产环境则不处理
if ($data['environment'] != 'PROD') {
    return;
}

// 通过获取bundle id判断属于哪款游戏
$bid = $data['bid'];

$unified = $data['unified_receipt'];

// 如果退款列表状态不合理
if ($unified['status'] !== 0) {
    return;
}
// 如果退款列表非生产环境则不处理
if ($unified['environment'] !== 'Production') {
    return;
}

// 每一笔退款订单
$latest_receipt_info = $unified['latest_receipt_info'];
foreach ($latest_receipt_info as $val) {
    // 如果不存在退款时间则认为此属于正常订单，非退款
    if (!isset($val['cancellation_date'])) {
        continue;
    }
    // 内购产品
    $product_id = $val['product_id'];
    // 苹果订单
    $transaction_id = $val['transaction_id'];
    // 通过苹果订单找到一一对应我方自身订单，进行校验、落地存储、玩家扣除资源或封号等处理。
    // ------
}
