 <dd>기존의 푸시 구독을 가져옵니다. 해당 구독에 대한 상세 정보를 담은 {{domxref("PushSubscription")}} 객체를 {{jsxref("Promise")}}로 반환합니다. 구독이 존재하지 않으면 프로미스는 <code>null</code>로 이행합니다.</dd>

 <dd>PushManager의 허가 상태로 이행하는 {{jsxref("Promise")}}를 반환합니다. 상태는 <code>'granted'</code>, <code>'denied'</code>, <code>'prompt'</code> 중 하나입니다.</dd>
 <dt>{{domxref("PushManager.subscribe()")}}</dt>
 <dd>푸시 서비스에 구독합니다. 해당 구독에 대한 상세 정보를 담은 {{domxref("PushSubscription")}} 객체를 {{jsxref("Promise")}}로 반환합니다. 현재 서비스 워커에 이전 구독이 존재하지 않으면 새로운 푸시 구독을 생성합니다.</dd>
