  title: Hookdeck Investigate Event Delivery Attempts
  summary: Resolve an event, list its delivery attempts, then read the latest attempt body.
  description: >-
    A debugging flow for understanding why an event delivered the way it did.
    The workflow reads a single event, lists all of its delivery attempts,
    branches on whether any attempts exist, and reads the most recent attempt to
    surface the destination response body. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
