Question

I'm inserting a new event on Google Calendar using a service account service@entreprise.tn .

I can't specify the organizer or the creator of an event . My code is:

            Organizer organizer = new Organizer().setEmail("user1@entreprise.tn").setSelf(true);
            Creator creator = new Creator().setEmail("user1@entreprise.tn").setSelf(true);

            Calendar service = Calendar_Utils.getCalendarService();
            Event event = new Event()
                         .setSummary("Google Calendar API")
                         .setOrganizer(organizer)
                         .setCreator(creator);

            DateTime startDateTime = new DateTime("2020-04-24T09:00:00.000Z");
            EventDateTime start = new EventDateTime()
                                  .setDateTime(startDateTime)
                                  .setTimeZone("Africa/Tunis");
            event.setStart(start);

            DateTime endDateTime = new DateTime("2020-04-24T10:30:00.000Z");
            EventDateTime end = new EventDateTime()
                                .setDateTime(endDateTime)
                                .setTimeZone("Africa/Tunis");
            event.setEnd(end);

            String calendarId = "primary";
            event = service.events().insert(calendarId, event).execute();
            System.out.printf("Event created: %s\n", event.getHtmlLink() + " - " + event.getOrganizer() + " - " + event.getCreator());

As result, the new event is inserted, but with organizer and creator service@entreprise.tn and not user1@entreprise.tn .

Could you please tell me how can I change my code to set the organizer to user1@entreprise.tn .

Thanks a lot.

Answer 1

Do an events.patch and update the organizer fields on the Event by default the organizer property is set to the person or service account which created the event.

Impersonation

If the service account has been set up with domain wide delegation to a gsuie domain you can impersonate one of the users on the domain and the organizer will be the user who was impersonated.

Answer 2

When you create an event with the service account, you need to impersonate the user on whose behalf the event shall be created

In Java you would do it as following:

    GoogleCredential getCredentials = new GoogleCredential.Builder()
     .setTransport(HTTP_TRANSPORT)
     .setJsonFactory(JSON_FACTORY)
     .setServiceAccountId(serviceAccount)
     .setServiceAccountPrivateKeyFromP12File(pk12)
     .setServiceAccountScopes(SCOPES)
     .setServiceAccountUser("user1@entreprise.tn") 
     .build();
