# REST API와 HTTP API 중에서 선택
<a name="http-api-vs-rest"></a>

REST API와 HTTP API는 모두 RESTful API 제품입니다. REST API는 HTTP API보다 더 많은 기능을 지원하지만 HTTP API는 최소한의 기능으로 설계되어 더 낮은 가격으로 제공될 수 있습니다. API 키, 클라이언트별 제한, 요청 검증, AWS WAF 통합 또는 프라이빗 API 엔드포인트와 같은 기능이 필요한 경우 REST API를 선택합니다. REST API에 포함된 기능이 필요하지 않은 경우 HTTP API를 선택합니다.

다음 섹션에는 REST API 및 HTTP API에서 사용할 수 있는 핵심 기능이 요약되어 있습니다. 필요한 경우 API Gateway 개발자 안내서의 REST API와 HTTP API 섹션을 탐색할 수 있는 추가 링크가 제공됩니다.

## 엔드포인트 유형
<a name="http-api-vs-rest.differences.endpoint-type"></a>

엔드포인트 유형은 API Gateway가 API용으로 생성하는 엔드포인트를 나타냅니다. 자세한 내용은 [API Gateway의 REST API에 대한 API 엔드포인트 유형](api-gateway-api-endpoint-types.md) 섹션을 참조하세요.
