代码示例（SDK）

您可以轻松地从常见的后端语言调用创建发票 API（/payment/crypto）。

如果您的后端不使用以下语言之一，只需向 https://api.payerscan.com/payment/crypto 发送 POST 请求，附带 JSON body 和 x-api-key header 即可。

JavaScript / Node.js (Axios)

const axios = require('axios');

async function createCryptoPayment() {
  try {
    const response = await axios.post(
      'https://api.payerscan.com/payment/crypto',
      {
        merchant_id: 'MID-XXXXXXXXXX',
        amount: 100,
        request_id: `ORDER_${Date.now()}`,
        name: 'Premium Sneakers',
        description: 'Team sponsorship.',
        callback_url: 'https://shop.com/webhook',
        completed_url: 'https://shop.com/success',
        expired_url: 'https://shop.com/cancel'
      },
      {
        headers: {
          'Content-Type': 'application/json',
          'x-api-key': 'YOUR_API_KEY_HERE'
        }
      }
    );

    console.log('发票已创建:', response.data.data.url_payment);
    // 将用户浏览器重定向到上方的 url_payment 链接
  } catch (error) {
    if (error.response) {
      console.error('API 错误:', error.response.data);
    } else {
      console.error('请求失败:', error.message);
    }
  }
}

createCryptoPayment();
