Gestire le impostazioni di assenza con l'API Gmail

Questo documento spiega come utilizzare il risponditore automatico nell'API Gmail.

Puoi utilizzare la risorsa settings per configurare una risposta automatica per un account.

Per informazioni su come ottenere o aggiornare le impostazioni del risponditore automatico, consulta la risorsa settings.

Configurare la risposta automatica

La risposta automatica richiede un oggetto e un corpo della risposta in formato HTML o testo normale. Imposta questi valori nell'oggetto VacationSettings. Puoi attivare la risposta automatica a tempo indeterminato o limitarla a un periodo di tempo specifico. Puoi anche limitare la risposta automatica ai contatti noti o ai membri del dominio.

I seguenti esempi di codice mostrano come impostare una risposta automatica per un periodo di tempo fisso e limitare le risposte agli utenti dello stesso dominio:

Per disattivare la risposta automatica, chiama il metodo settings.updateVacation e imposta il campo enableAutoReply dell'oggetto VacationSettings su false. Se imposti un valore endTime, Gmail disattiva la risposta automatica una volta trascorso il tempo specificato.
