  title: GitLab Request and Approve Project Access
  summary: Request access to a project, then approve that same requester.
  description: >-
    A two-actor onboarding flow. The workflow first submits an access request for
    the authenticated user to a project, captures the resulting requester id, and
    then approves that requester at the supplied access level. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
