  title: Backblaze Rotate Application Key
  summary: Authorize, create a replacement application key, then delete the old key it supersedes.
  description: >-
    A safe key-rotation chain that always creates the replacement before
    revoking the old credential, so access is never interrupted. The account is
    authorized, a new key is minted with the desired capabilities, and the
    previous applicationKeyId is then deleted. The accountId from authorize
    feeds the create call and the old key id is supplied as an input to the
    delete call. Every step spells out its request inline so the flow can be
    read and executed without opening the underlying OpenAPI description.
