代码示例

• 代收下单支持法币与数字货币(USDT/BTC/ETH/TRX)交易
• 如果您想使用数字货币交易,请设置orderType=1;
• 通过商户用户ID来区分不同用户的交易
• 我们的数字代收订单分两个模式：有单模式和无单模式
• Ex: 收银台版本(v1.0和v3.0属于有单模式版本;v2.0和v4.0属于无单模式)
• Ex: v1.0、v2.0-只展示支付地址
• Ex: v3.0、v4.0-展示二维码和支付地址两种方式
• 您需要告诉我们您想使用何种数字货币和链网络进行交易(TRC20/BEP20/OMNI/ERC20/TRX)
• 我们后续会推出其他币种和网络的交易,敬请期待
