建立 smart home 動作後，下一步是在執行要求中加入功能，以處理 Google Assistant 可辨識的智慧型住宅意圖和傳回回應。
識別使用者
Assistant 會使用 Authorization 標頭中 OAuth 2.0 伺服器提供的存取權杖，向 smart home 動作的執行要求執行要求。
POST /fulfillment HTTP/1.1 Host: smarthome.example.com Content-Type: application/json Authorization: Bearer ACCESS_TOKEN
回應要求之前，執行要求邏輯應確認這個權杖憑證有效，並決定相關聯的使用者帳戶。如果存取權杖無效，執行要求應會傳回 HTTP 401 Unauthorized 錯誤。
列出裝置及其功能
Assistant 會將 action.devices.SYNC 意圖傳送至您的執行要求，要求取得與特定使用者相關聯的裝置清單，以及這項功能的功能。您的執行要求必須在 SYNC 回應的 agentUserId 欄位中，為每個使用者傳回不重複的 ID。這個 ID 必須是不可變更的值，才能代表您的雲端服務。不建議依據使用者可以變更的設定提供電子郵件地址或其他屬性。
SYNC 回應的 devices 欄位包含使用者授權存取 Assistant 的所有裝置、支援的類型和特性，以及為該裝置設定相關設定的屬性。
系統會在帳戶連結期間或使用者手動重新同步處理裝置時觸發 SYNC 意圖。如果使用者的裝置清單、支援的特性或屬性值有所變更，請使用要求同步處理來觸發新的 SYNC 意圖，並將更新回報給 Google。
