pinduoduo（商品优惠券）API接口

为了进行电商平台的API开发，首先我们需要做下面几件事情。

1）开发者注册一个账号

2）然后为每个pinduoduo应用注册一个应用程序键（App Key) 。

3）下载pinduoduo API的SDK并掌握基本的API基础知识和调用

4）利用SDK接口和对象，传入AppKey或者必要的时候获取并传入SessionKey来进行程序开发。

5）利用alibaba平台的文档中心和API测试工具，对接口进行测试。从而了解返回信息，方便程序获取。

以上是一般pinduoduo API应用开发的关键流程，其中通过pinduoduo文档中心和API测试工具，进行概念了解和接口信息查询很重要。因为这些数据就是我们需要在逐步显示出来的。pinduoduo的API很多，不过都分为了好几个领域，慢慢就会了解深入了。
