为了进行电商平台API开发，我们需要做下面几件事情。
1）开发者注册一个账号
2）然后在平台应用注册一个应用程序键（App Key) 。
3）下载平台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）利用平台提供的API文档中心和测试工具，对接口进行测试。从而了解返回信息，方便程序获取。
以上是电商平台的API应用开发的关键流程，其中通过平台文档中心和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。lazada 的API很多，不过都分为了好几个领域，慢慢就会了解深入了。
