微店API开发全攻略：解锁电商数据与业务自动化的核心能力

# 批量更新库存（Python示例）  
def update_sku(stock_list):  
    url = "https://api.weidian.com/sku/update"  
    headers = {"Authorization": "Bearer {access_token}"}  
    for sku in stock_list:  
        payload = {  
            "num_iid": sku["num_iid"],  
            "sku_id": sku["sku_id"],  
            "quantity": sku["stock"]  
        }  
        response = requests.post(url, json=payload, headers=headers)  
        if response.json()["code"] != 0:  
            log_error(f"库存更新失败：{sku}")

// Java订单状态监听（Spring Boot）  
@PostMapping("/order/webhook")  
public ResponseEntity<String> handleWebhook(@RequestBody OrderEvent event) {  
    if ("TRADE_SUCCESS".equals(event.getStatus())) {  
        orderService.triggerShipment(event.getOrderId());  
    }  
    return ResponseEntity.ok("ACK");  
}

// 发放优惠券（Node.js示例）  
async function sendCoupon(userId, couponTemplateId) {  
  const result = await weidianApi.request({  
    method: 'POST',  
    path: '/promotion/coupon/send',  
    data: {  
      user_id: userId,  
      template_id: couponTemplateId  
    }  
  });  
  return result.code === 0;  
}

用户下单 → 微店Webhook通知 → ERP系统接单 → WMS发货 → 回传物流单号 → 短信通知用户
