チャットグループ、大規模ツール統合、ファイル統合、統合検索であることが分かります。 2014 年末の時点で、Slack には電子メール、テキスト メッセージ、Google ドライブ、Twitter、Trello、Asana、GitHub など 65 のツールとサービスが統合されており、断片化された企業のさまざまなコミュニケーションやコラボレーションを 1 つにまとめることができます。いくつかの重要な概念:
ワークスペース: 非常に優れたワークスペースです。ユーザーはさまざまなワークスペースに参加したり作成したりできます。多くの場合、ワークスペースの名前と URL は会社名になります。
チャネル: チャネルはさまざまなチームまたはトピックに分けることができ、チャネル内のメンバーがチャネル内の情報を共有する WeChat と同等のものとして理解することもできます。
3. 事前準備slack設定をエリアに追加し、チャネルを選択して Webhook URL を保存します。後で Webhook 実装プログラムを使用してチャネルにメッセージを送信します。
