Microsoft Teams のシステムメッセージを取得する

[アーティクル]
03/26/2023

Microsoft Teams は、Microsoft Graph API を利用して、イベント用のシステムメッセージを生成します。イベントには、チャットに追加されたメンバー、更新されたチーム名、更新されたチャネルの説明が含まれます。システムメッセージを使用すると、発信者は、チーム、チャネル、またはチャットで発生したイベントに関する分析情報を得ることができます。

Microsoft Graph は、chatMessage GET 操作およびチャットメッセージとチャネルメッセージの変更通知の一部としてシステムメッセージを公開します。

システムメッセージは、chatMessage オブジェクトとして表示されます。この場合、messageType プロパティは、systemEventMessage に設定され、eventDetail プロパティはイベントの詳細を提供します。

サポート対象の GET 操作

次の GET 操作は、システムメッセージをサポートします。

GET /teams/{team-id}/channel/{channel-id}/messages
GET /teams/{team-td}/channel/{channel-id}/messages/{message-id}
GET /chats/{chat-id}/messages
GET /chats/{chat-id}/messages/{message-id}

詳細については、「chatMessage」を参照してください。

サポート対象の変更通知

次の変更通知は、システムメッセージをサポートします。

チャネルのメッセージに登録する - /teams/{team-id}/channels/{channel-id}/messages
チャットのメッセージに登録する - /chats/{chat-id}/messages

詳細については、「メッセージの変更通知」を参照してください。
