# Apri un changeset

Richiede `sites:write`. Non costa crediti.

Un changeset prevede quattro passaggi: aprirlo, [preparare i file](/docs/api/changesets/patch), poi [confermarlo](/docs/api/changesets/commit) o [abbandonarlo](/docs/api/changesets/abandon). Rimane aperto per 10 minuti, poi viene confermato se valido oppure abbandonato.

Usa un changeset quando una modifica richiede più chiamate, per esempio per
aggiungere una pagina, i suoi contenuti e la sua immagine. Non serve per una
singola chiamata che modifica più file: [Modifica i file](/docs/api/files/commit)
crea già una sola voce.
