CloudKit Web Services
The CloudKit Web Services REST API is structured as /database/1/{container}/{environment}/{database}/{operation}, where database is one of public, private, or shared and environment is development or production. Operations include records lookup, query, modify, delete, zone create/list/delete, subscription create/list/delete, asset upload, user info and changes. Calls are authenticated using an API token for user-authenticated access (with ckWebAuthToken) or a server-to-server ECDSA key for backend access.
