# Short Names of Ledger Entries

Some API methods, specifically the [account_objects method](/docs/references/http-websocket-apis/public-api-methods/account-methods/account_objects) and [ledger_data method](/docs/references/http-websocket-apis/public-api-methods/ledger-methods/ledger_data), allow filtering the ledger entries they return based on the type of ledger entry. The type field you specify can use either the canonical name of the [ledger entry](/ja/docs/references/protocol/ledger-data/ledger-entry-types) or a short name, as in the following table.

The "Ownable" column indicates whether the ledger entry type can appear in owner directories. Ledger entries that are not ownable cannot appear in `account_objects` responses and cannot be used as a `type` filter in that method.
