paypal sandbox 开发环境搭建

1， paypal

  • https://developer.paypal.com/ 注册开发者账号

  • 创建sandbox测试账号

  • https://sandbox.paypal.com/ 登陆上面创建的商户收款账号

  • 配置ipn 通知,按照图片中的 1，2，3，4顺序点击

    点击图片中4的更新按钮跳转到如下界面

    编辑后保存

  • 配置支付成功后跳转到的页面地址

    点击上图中2的更新按钮，到如下界面

    保存，配置完成

2，服务器接口实现，需要实现两个页面，一个是支付完成回调页面，一个是支付完成后跳转到的页面，以php为例
