概览

Hosted Payment Page (HPP) 方案让你通过将客户安全地重定向到 UQPay 托管的收银台页面来受理支付。敏感支付数据由 UQPay 安全处理。

​
使用方式

​
  1. 创建 PaymentIntent

调用 Create Payment Intent 接口发起交易，并获取 SDK 所需的凭证。 API 参考： Create Payment Intent

}

​
  1. 提取参数

从步骤 1 的 API 响应中，提取以下字段传给你的前端：
  • client_secret
  • payment_intent_id
  • currency

​
  1. 初始化 SDK

在前端安装 UQPay Checkout SDK，并使用上述参数将用户重定向。 SDK 包： @uqpay/checkout-sdk 
import { init } from '@uqpay/checkout-sdk';

async function redirectToPayment() {
  // Initialize SDK
  const uqpay = await init({
    env: 'production', // 'sandbox' | 'production'
    enabledElements: ['payments']
  });

  // Redirect to payment page
  await uqpay.payments.redirectToCheckout({
    mode: 'payment',
    currency: 'USD',
    intent_id: 'pi_1234567890',
    client_secret: 'pi_1234567890_secret_abcdef',
    success_url: 'https://yoursite.com/success', // Optional
    failure_url: 'https://yoursite.com/failure', // Optional
  });
}

  1. 获取支付结果

可以通过以下任意方式确认支付的最终状态： 配置你的服务端监听 UQPay 发出的异步通知。这是更新订单状态最可靠的方式。 Webhook 参考：

​
方式 B：主动查询

你的服务端可以主动通过 API 查询 PaymentIntent 的状态。 API 参考： Retrieve Payment Intent
