Get the list meetings from google hangouts meet

Question

I'm asking if it's possible to retrieve the lists of meetings done with Google Hangout Meet API in Java?. After googling, I can't figure it out.

UPDATED - 1: With Google Calendar, I made:

        Calendar service = getCalendarService();
        List<Event> items = new ArrayList<Event>();
        String pageToken = null;
        do {
          Events events = service.events().list("service-account-esprit@my-first-project-2587777.iam.gserviceaccount.com").setPageToken(pageToken).execute();
          items = events.getItems();
          for (Event event : items) {
            System.out.println(event.getSummary());
          }
          pageToken = events.getNextPageToken();
        } while (pageToken != null);

Which the method getCredentials() is:

public static Credential getCredentials() throws IOException
{
    java.io.File clientSecretFilePath = new java.io.File(CREDENTIALS_FOLDER, CLIENT_SECRET_FILE_NAME);

    InputStream in = new FileInputStream(clientSecretFilePath);
    GoogleClientSecrets clientSecrets = GoogleClientSecrets.load(JSON_FACTORY, new InputStreamReader(in));

    SCOPES.add(CalendarScopes.CALENDAR_READONLY);

    GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES).setDataStoreFactory(DATA_STORE_FACTORY).setAccessType("offline").build();
    Credential credential = new AuthorizationCodeInstalledApp(flow, new LocalServerReceiver()).authorize("user");

    return credential;
}

UPDATED - 2:

So, I missed enable G Suite domain wide delegation. I fixed that as presented by that capture I replaces the old credentials.json by my-first-project-274515-ba944be8b749.json (file resulted after creating the service account).

Then, I made Events events = service.events().list("service-account-esprit@my-first-project-2587777.iam.gserviceaccount.com").setPageToken(pageToken).execute();

I share the calendar with service-account-esprit@my-first-project-2587777.iam.gserviceaccount.com

I enabled Google calendar Api, too.

But I got that exception:

Exception in thread "main" java.lang.IllegalArgumentException at com.google.api.client.repackaged.com.google.common.base.Preconditions.checkArgument(Preconditions.java:108) at com.google.api.client.util.Preconditions.checkArgument(Preconditions.java:37) at com.google.api.client.googleapis.auth.oauth2.GoogleClientSecrets.getDetails(GoogleClientSecrets.java:82) at com.google.api.client.googleapis.auth.oauth2.GoogleAuthorizationCodeFlow$Builder.(GoogleAuthorizationCodeFlow.java:197) at tn.esprit.spring.google.calendar.Calendar_Utils.getCredentials(Calendar_Utils.java:75) at tn.esprit.spring.google.calendar.Calendar_Utils.getCalendarService(Calendar_Utils.java:87) at tn.esprit.spring.google.calendar.Calendar_Utils.main(Calendar_Utils.java:95)

--> I got error on GoogleAuthorizationCodeFlow flow = new GoogleAuthorizationCodeFlow.Builder(HTTP_TRANSPORT, JSON_FACTORY, clientSecrets, SCOPES).setDataStoreFactory(DATA_STORE_FACTORY).setAccessType("offline").build(); I can't figure it out. Could you please tell me what I missed ?. Any suggestion is appreciated. Big thanks.

Answer 1

You can try:

Events events = service.events().list([email protected])
                .setOrderBy("startTime")
                .setSingleEvents(true)
                .execute();

HTH.
