# 在 REST API 和 HTTP API 之间进行选择
<a name="http-api-vs-rest"></a>

REST API 和 HTTP API 都是 RESTful API 产品。REST API 支持的功能比 HTTP API 多，而 HTTP API 在设计时功能就极少，因此能够以更低的价格提供。如果您需要如 API 密钥、每客户端节流、请求验证、AWS WAF 集成或私有 API 端点等功能，请选择 REST API。如果您不需要 REST API 中包含的功能，请选择 HTTP API。

以下各节汇总了 REST API 和 HTTP API 中可用的核心功能。必要时，还会提供其他链接，以便于在《API Gateway 开发人员指南》的 REST API 部分与 HTTP API 部分之间导航。

## 端点类型
<a name="http-api-vs-rest.differences.endpoint-type"></a>

端点类型是指 API Gateway 为 API 创建的端点。有关更多信息，请参阅 [API Gateway 中针对 REST API 的 API 端点类型](api-gateway-api-endpoint-types.md)。
