  title: Android Defer a Subscription Renewal
  summary: Read a subscriber's current expiry time and push it forward as a goodwill credit or service-outage make-good.
  description: >-
    Deferral is how you give a subscriber free extra time without refunding or
    re-billing them — the retention lever for goodwill credits, service outage
    compensation, and support-desk saves. The defer endpoint requires the
    caller to pass the subscription's current expiry time as
    expectedExpiryTimeMillis, and it rejects the request if that value does not
    match what Google Play holds. This workflow therefore reads the live expiry
    first and feeds it straight into the defer call, which removes the race that
    makes hand-rolled deferral code fail. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.

  summary: Read the current subscription expiry, defer it to a desired future time, and confirm the new expiry.
  description: >-
    Fetches the subscription purchase to obtain the authoritative
    expiryTimeMillis, defers the subscription to the caller's desired expiry
    using that value as the expected expiry, and reads the purchase back to
    confirm the new expiry time took effect.
  inputs:
    type: object
    required:
    - packageName
    - subscriptionId
    - purchaseToken
    - desiredExpiryTimeMillis
    properties:
      packageName:
        type: string
        description: The package name of the application (e.g. com.example.myapp).
      subscriptionId:
        type: string
        description: The subscription product id the purchase relates to.
      purchaseToken:
        type: string
        description: The subscription purchase token supplied to the app by Google Play.
      desiredExpiryTimeMillis:
        type: string
        description: >-
          The new expiry time in milliseconds since the Epoch. Must be later
          than the subscription's current expiry time.
  steps:
  - stepId: readSubscription
    description: >-
      Read the subscription purchase to obtain the authoritative current expiry
      time, which the defer call requires as its expected expiry.

  - stepId: deferSubscription
    description: >-
      Defer the subscription to the desired expiry time. The expected expiry is
      taken from the live read so Google Play can confirm no renewal or
      cancellation slipped in between the two calls.
