Q：“当面付”和“JSAPI支付”有什么区别？
Q：我的小程序已接入过当面付，如何快速切换到JSAPI支付？
| 序号 | 接入流程 | 使用的接口 | 当面付 | JSAPI支付 |
|---|---|---|---|---|
| 1 | 发送订单信息 | my.request | - | 无变化 |
| 2 | 创建交易订单 | alipay.trade.create（统一收单交易创建接口） | product_code：FACE_TO_FACE_PAYMENT | product_code：JSAPI_PAY新增字段：op_app_id（小程序支付中，商户实际经营主体的小程序应用的 APPID，指在小程序中，拉起收银台支付时的小程序应用的 APPID） |
| 3 | 唤起收银台支付 | my.tradePay（发起支付） | 无限制 | 必须调 my.tradePay（发起支付）接口才能唤起收银台 |
| 4 | 异步通知 | 在 alipay.trade.create（统一收单交易创建接口）设置异步通知（notify_url） | - | 无变化 |
| 5 | 交易辅助（查询、退款、撤销、关闭） | alipay.trade.query（统一收单交易查询）alipay.trade.refund（统一收单交易退款接口）alipay.trade.cancel（统一收单交易撤销接口）alipay.trade.close（统一收单交易关闭接 口） | - | 无变化 |
