  title: Swell Create and Verify Subscription
  summary: Create a recurring subscription for an account and product, then read it back.
  description: >-
    Stands up recurring revenue for a headless store. The workflow creates a
    subscription tying an account to a subscription product and plan with a
    billing interval, captures the new subscription id, and reads it back to
    confirm its status and billing period. Each step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
