本文就从API接口的维度，浅析API的概念以及为什么要了解它
一、API的概念
API，官方定义为应用程序编程接口。就是把是一些预先定义的接口，用来提供应用程序与开发人员基于某软件或硬件得以访问的一组例程，而又无需访问源码，或理解内部工作机制的细节。
二、为什么要懂API文档 既然API如此复杂，又不属于PM的工作范畴，我们为何需要大费周章的理解它呢，我们的目的是什么。
- 明确需要的接口服务
API分为很多种，最基础也是产品最需要的诸如短信API，地图API，语音API等，如果我们的产品涉及到此方面的功能，那就必须了解这方面的API以便于在需求设计阶段考虑更全面。
- 掌握项目开发的工作量，网合理安排计划
这里说白一点就是防止被程序员欺骗。你走过去，发现程序员正在勤勤恳恳，对不起，人家在做外包，就是欺负你代码看不懂，气不气？但是如果你知道接口的难度和工作量，规定他在多久之内给你，就不会出现拖延项目的情况，也更有利于项目流程的更进。
- 联调测试，识别项目风险点
一些关键接口、数据量大需要进行大数据压测的接口，必须经过联掉测试，测出它的最大访问量，并对其进行优化或者设置限制，防止系统崩溃。
- 方便项目对接
PM懂一点技术，就不会闹出明明不能做，却还非要程序员做出来的笑话了。从这个角度看，也更有利于PM和程序员之间的团队沟通与和谐，避免矛盾，不至于弄翻友谊的小船。了解API可以使PM对技术理解更深刻，更好地衡量开发工作量和制定功能内容。
三、举例说明API的重要性
有一杯密封果汁叫做数据库；果汁上面插着吸管，叫做API。如果你想喝到杯子里的果汁，由于它是密封的，你只能依靠吸管插入，否则你就喝不到果汁。
在这个故事中，你属于某系统，你想获得果汁，就必须通过吸管，也就是接口，API来实现，而且这个API是数据库的唯一API。这样说来，API是一种完善项目功能，提高产品价值的辅助工具。
缺点：
因为API是借助了第三方软件，接入方在使用其他软件包功能的同时相当于为自身插入了一个监控，会有数据泄露给第三方的危险。所以如果是公司的核心功能，最好是使用企业内部的API。
