Le *azioni* sono estratti di codice da programmi più grandi e devono essere eseguite nel contesto. Sebbene le azioni mostrino come richiamare le singole funzioni del servizio, è possibile visualizzarle contestualizzate negli scenari correlati. Ogni esempio include un link al codice sorgente completo, in cui vengono fornite le istruzioni su come configurare ed eseguire il codice nel contesto. **Topics** + [Azioni](#actions) ## Azioni ### `CreateGroup` Il seguente esempio di codice mostra come utilizzare`CreateGroup`. **SDK per Java 2.x** C'è altro da fare GitHub.
