  title: Svix Send Message and Confirm Delivery
  summary: Send a message to an existing application and poll its attempts until delivery succeeds.
  description: >-
    A delivery-confirmation flow for an application that already has endpoints
    configured. The workflow publishes a message, fetches it back to confirm it
    was accepted, and then polls the message's delivery attempts until a
    successful attempt is recorded. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
