电商企业从接收订单-配货-打印快递单到后期的快递员收件-快递配送-轨迹查询-签收短信通知等，都需要快递接口的接入。整理目前可以实现如上服务的有

1.各家快递公司：提供快递查询、电子面单打印等
2.快递100：提供在线寄件、快递查询等
3.菜鸟：提供快递查询、电子面单打印等
4.快递鸟：提供预约寄件、快递查询、电子面单打印、代收货款、短信服务等

各家快递公司提供的是一级接口，快递100、菜鸟和快递鸟是集成接口，对于使用快递比较多的企业来说，集成接口相对更好维护一些。所以一般电商都会选择集成的接口。
快递鸟是专做快递api接口服务的，接口类型也比较全一些，以下以快递鸟接口对接为例（提供的接口demo均为JAVA，如有其它语言demo需要请自行到官网下载）

对接流程：进入快递鸟官网申请接口——对接——联调测试——上线

预约取件-在线预约寄件
