  title: Amplitude Feature Flag Rollout
  summary: Create a feature flag, read it back, enable it, and confirm it appears in the flag list.
  description: >-
    Automates a feature flag rollout through the Amplitude Experiment Management
    API. The workflow creates a new flag with variants, retrieves it by its
    returned ID to confirm the configuration, patches it to enable the flag, and
    lists all flags to confirm the rollout. This is the pattern teams wire into
    CI/CD pipelines to manage flag lifecycle without the Amplitude UI. All steps
    authenticate with a Management API key as a bearer token. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
