什么是 API？电商API接口的用处是什么？

概述

应用编程接口（API）是一组用于构建和集成应用软件的定义和协议。

API 的工作原理是什么？

通过 API，您无需了解实施原理，也能将您的产品或服务与其他的互通。这样可以简化应用的开发，节省时间和成本。在您开发新的工具和产品，或管理现有工具和产品时，强大灵活的 API 可以帮助您简化设计、管理和使用，并带来更多创新机遇。

API 有时被视为合同，而合同文本则代表了各方之间的协议：如果一方以特定方式发送远程请求，该协议规定了另一方的软件将如何做出响应。

由于 API 简化了开发人员将新应用组件集成到现有基础架构中的方式，继而也对业务和 IT 团队之间的协作提供了帮助。随着数字市场日新月异，业务需求通常也会出现迅速变化，新的竞争对手利用新的应用即可改变整个行业。为了保持竞争力，支持快速开发和部署创新服务尤为重要。云原生应用开发是提高开发速度的一个明确办法，依赖于通过 API 连接微服务应用架构。

API 是通过云原生应用开发来连接您自己的基础架构的一个简化方式，此外还支持您向客户和其他外部用户分享您的数据。公共 API 有着独特的商业价值，因其可以简化和扩展您与合作伙伴的联系方式，并有望支持您从数据中实现盈利（Google Maps API 便是其中一个广为人知的案例）。
