description: >-
  Kapost publishes outbound webhooks (no AsyncAPI document). You register a
  destination URL in the Kapost instance webhook settings and Kapost sends an
  HTTP POST with a JSON body whenever content is created, modified, deleted, or
  published. A test button is available on the webhook settings page. You may
  configure an SSL endpoint so payloads are encrypted in transit; the docs do
  not document an HMAC signature / signing-secret verification mechanism.
