  description: >-
    Strapi includes a built-in webhook system that notifies external services
    whenever certain events occur in the CMS. Rather than polling the Strapi
    API for changes, you can configure Strapi to send HTTP POST requests to
    a specified URL when content entries or media assets are created, updated,
    deleted, published, or unpublished. Webhooks are configured through the
    Strapi admin panel under Settings > Webhooks and include a custom
    X-Strapi-Event header identifying the event type. Global webhook headers
    can also be configured in the server configuration file.

    description: >-
      The webhook delivery channel. Strapi sends HTTP POST requests to the
      configured URL whenever a subscribed event occurs. Each request
      includes an X-Strapi-Event header with the event type and any
      globally configured headers.

      description: >-
        Strapi publishes webhook events to this channel when content entries
        or media assets are created, updated, deleted, published, or
        unpublished. The receiving application processes these events to
        trigger downstream actions such as cache invalidation, search index
        updates, or notifications.
