# 在 REST API 與 HTTP API 之間選擇
<a name="http-api-vs-rest"></a>

REST API 和 HTTP API 都是 RESTful API 產品。REST API 支援比 HTTP API 更多的功能，而 HTTP API 的設計具有最少功能，因此它們能以較低的價格提供。如果您需要 API 金鑰、個別用戶端限制、請求驗證、 AWS WAF 整合或私有 API 端點等功能，請選擇 REST API。如果您不需要 REST API 中包含的功能，請選擇 HTTP API。

下節摘要說明REST API 和 HTTP API 中可用的核心功能。必要時會提供其他連結，以在《API Gateway 開發人員指南》的 REST API 和 HTTP API 章節之間導覽。

## 端點類型
<a name="http-api-vs-rest.differences.endpoint-type"></a>

端點類型是指 API Gateway 為您的 API 建立的端點。如需詳細資訊，請參閱[API Gateway 中 REST API 的 API 端點類型](api-gateway-api-endpoint-types.md)。
