versioning:
  scheme: explicit-major-minor-in-request
  current: apiVersion 2 / apiVersionMinor 0
  description: >-
    The Google Pay client APIs version in the request body, not in a URL path: every
    PaymentDataRequest and IsReadyToPayRequest carries apiVersion and apiVersionMinor. The
    Google Pay UCP payment-handler config schema pins both with JSON Schema const — api_version
    const 2, api_version_minor const 0 — which is the only machine-readable statement of the
    current version Google publishes.

deprecation_policy:
  published: false
  sunset_header: false
  deprecation_header: false
  note: >-
    Searched the Google Pay support, release-notes and FAQ trees for a versioning or deprecation
    policy and found none. Google announces changes in dated release notes, but publishes no
    stated deprecation window, no sunset commitment, and returns no RFC 8594 Sunset/Deprecation
    headers on any Google Pay surface. Because no policy is published, no `Deprecation` pointer
    was wired into apis.yml — an absent policy must not be advertised as a present one.
sla:
  published: false
  note: >-
    No public SLA for the Google Pay API. The Google Pay API Terms of Service
    (payments.developers.google.com/terms/sellertos) governs the relationship; it is a terms
    document, not an availability commitment with credits.
