  title: Backblaze Provision Bucket and Upload First File
  summary: Authorize, create a bucket, get its upload URL, and upload the first file end to end.
  description: >-
    A full greenfield onboarding chain that takes an empty account to a bucket
    holding its first object. It authorizes the account for the token and
    accountId, creates a new bucket, requests an upload URL scoped to that
    freshly created bucket, and uploads the initial file. The newly created
    bucketId flows from the create step directly into the upload-URL request,
    demonstrating cross-step data handoff. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
