  title: Runloop Publish an Object Artifact
  summary: Create a storage object, mark its upload complete to make it read-only, then generate a presigned download URL for it.
  description: >-
    Objects are Runloop's stored data artifacts. This workflow creates an object
    with a name and content type, completes its upload to transition it from the
    UPLOADING state into the read-only state, and then generates a time limited
    presigned download URL so the artifact can be retrieved. Every step spells out
    its request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
