  title: Apple CloudKit Web Services Assets API
  description: 'Best-effort OpenAPI 3.1 description of Apple CloudKit Web Services, the

    REST surface that lets non-Apple-platform clients read and write data in

    a CloudKit container''s public, private, or shared database. Operations

    cover records, zones, subscriptions, assets, users, and database/zone

    changes. Authentication uses either a CloudKit API token (for end-user

    authenticated requests; the token is appended as the `ckAPIToken` query

    parameter) or a server-to-server ECDSA signature (X-Apple-CloudKit-Request-*

    headers) for backend access.
