  title: Android Refund a Play Order
  summary: Resolve a purchase token to its Google Play order id, refund that order, and optionally revoke the entitlement.
  description: >-
    Support desks work in purchase tokens, but the refund endpoint works in
    order ids. This workflow closes that gap: it verifies the in-app product
    purchase, reads the authoritative orderId out of the response, and refunds
    that order — so the refund is always issued against an order that was just
    confirmed to exist rather than an id pasted from a support ticket. The
    revoke query flag decides whether the user loses access immediately or keeps
    it, which is the difference between a goodwill refund and an enforcement
    action. Every step spells out its request inline so the flow can be read and
    executed without opening the underlying OpenAPI description.
