手写快递单太麻烦了，公司的订单又多，每次都写不过来，还容易出错，直接电子化在打印快递单就快了，不过现在有些人不懂怎么批量对接多个快递的电子面单，这里就给大家讲解讲解，希望对大家有用。

首先需要提前购买电子面单单号才能打印，这里给大家介绍对接电子面单接口对接和在线申请电子面单账号的方法，

快递鸟有电子面单api，后台系统直接对接很是方便，不过也遇到了好些问题。

不难是不难，但是遇到的坑着实是不少，特此记录一下。

快递鸟电子面单API地址：http://www.kdniao.com/api-eorder

都是在正式环境下，申请对应的商户id等一系列东西。

在对应的快递鸟后台，可以进行如下的批量打印。
