  title: Amplitude Experiment Lifecycle
  summary: Create an A/B experiment, read it back, start it by enabling, and confirm it in the experiment list.
  description: >-
    Manages an A/B test experiment through the Amplitude Experiment Management
    API. The workflow creates a new experiment with control and treatment
    variants, retrieves it by ID to confirm its configuration, patches it to
    enable it, and lists all experiments to confirm the experiment is live. 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.
