参考：https://learnku.com/articles/26282  
SDK地址： http://paypal.github.io/PayPal-PHP-SDK/

## 步骤 ##

1.注册账号 认证 直到能正常转账  
2.下载SDK  
3.撸代码 沙盒测试  
4.正式环境测试

### 1.注册账号 ###

商家控制台：  
https://developer.paypal.com  
开发者中心：  
https://developer.paypal.com/developer/accounts/

**注意**：看文档可以挂梯子，进控制台不要，不然会打不开。

#### 创建沙盒支付账号 ####

默认会带两个的，一个商家一个私人。

#### 获取APP 的 ID和Secret ####

创建你的APP  
https://developer.paypal.com/developer/applications/create?env=live

然后就可以看到ID和Secret

**以上步骤不会的可以多点点，然后翻译下网页，我相信你可以的。**

### 2.下载SDK ###

首先你要会composer  
`https://docs.phpcomposer.com/00-intro.html`  
composer.json加入：

"alibabacloud/sdk": "^1.8",
    "paypal/rest-api-sdk-php":

然后

composer update

### 3. 开始撸代码 ###
