API其实就是应用程序接口(Application Programming Interface)的简称。API 是一些功能、定义或者协议的集合，提供应用程序或者程序开发人员基于软件访问一组例程的能力，对外封装完善，调用时无需学习 API内部源码，依据 API文档功能说明书来使用即可。
那么API到底是一种什么技术呢？
如今具有开放式的业务体系结构将是下一代网络的重要特征之一。其中，关键的技术之一就是网络控制与应用层之间的应用程序接口(API)。通过应用程序接口，业务开发商 、独立软件提供商 (ISV)等第三方应用可以获得使用现有网络资源的能力 ，从而方便 、灵活地为客户提供所需的业务。API接口已经深入应用到各个网页与APP中。
