  title: Brevo Webhooks API
  description: >-
    The Brevo Webhooks API allows developers to receive real-time
    notifications when events occur across transactional emails, marketing
    campaigns, and conversations. By configuring webhook subscriptions,
    applications can automatically receive data for events such as email
    deliveries, opens, clicks, bounces, spam reports, and unsubscribes. This
    eliminates the need for polling and enables event-driven integrations that
    respond immediately to changes in messaging activity.
