APIs-Google 是 Google API 所使用的使用者代理程式，用途是提供推播通知訊息。
應用程式開發人員可以要求收到這些通知，如此一來，他們就不必持續輪詢 Google 伺服器，確認感興趣的資源是否有所異動。為了確保這項服務不會遭到濫用，當開發人員要將某個網域的網址登記為接收訊息的位置時，Google 會要求他們先驗證自己擁有該網域。
APIs-Google 如何存取網站
APIs-Google 會使用 HTTPS POST 要求來傳送每一個推播通知。如果因為暫時性的錯誤情況而導致要求失敗，APIs-Google 會重新傳送通知。如果要求依然失敗，APIs-Google 會按指數輪詢的方式繼續重試，最長可達數天時間。
