Standard Webhooks・MCP に対応

Webhook 統合インテグレーション

API を 1 回呼ぶだけで、署名付きの Webhook を送信し、届かなかった場合は自動で再送します。どのサービスの Webhook がどこで止まっているかも、管理画面で確認できます。

3 つのプロジェクト（請求サービス・会員アプリ・予約システム）から送った Webhook を 1 か所でまとめて送り、失敗した送信先は Slack に知らせる図

既存のサービスへの組み込み

イベントが発生した箇所で POST /v1/messages を呼び出すだけです。送信先への配送、署名、再送は Webhook Admin が行います。
