Google calendar API do not return events list

Recently after adding new events in Google calendar and try to fetch it from Google calendar API, I never get the new events list for the primary calendarId of my account.

Also I tried to fetch from developer console: https://developers.google.com/google-apps/calendar/v3/reference/events/list#try-it which gives the same empty list of items as response, even though the future events exists.

But I am able to fetch the events list of other calendar list. eg. Holidays, shared calendar from friends etc.

Are you authenticated? Do you get any error? Could you try performing an insert event operation on your primary calendar via the #try-it and see if that event gets listed? – luc
Yes, creation of events from the API from my primary calendarId is not an issue. I see that events gets created in the calendar. But when I try to fetch these events from the API, I get nothing in the response. – Suhas Giriraj
More questions: Can you perform a get for the event you just insterted and see if it is there? Can you see those events in the web UI? – luc
@SuhasGiriraj Was this issue resolved? – Matt
Same problem here. A secondary calendar with plenty of recurring events (visible in web GUI) but using python API, events().list() does NOT return any events. Setting singleEvents=True returns the instances, but that list is way too big so not a proper solution. Bug in google calendar API? – Davy

I also had the problem of events().list(calendarId=<calendar_id>, singleEvents=False) not returning any events (using python API). I tested with a secondary calendar with one recurring event. Solved by adding parameter maxResults=9999. It turned out that maxResults value 1413 or higher is needed to return the event. Weird, seems to be a bug.

Try adding singleEvents:true to your request.

I was having the same issue. In my case, using Javascript, this works (returns several single, non-recurring events) : 

  var calendar = googleapis.calendar('v3');
  calendar.events.list({
    auth: auth,
    calendarId: 'primary',
    timeMin: (new Date()).toISOString(),
    maxResults: 10,
    singleEvents: true,
    orderBy: 'startTime'
  }, function(err, response) {
    if (err) {
      console.log('The API returned an error: ' + err);
      return callback(err);
    }
    console.log(response); 
    var events = response.items;
    if (events.length == 0) {
      console.log('No upcoming events found.');
    } else {
      console.log('Upcoming 10 events:');
      for (var i = 0; i < events.length; i++) {
        var event = events[i];
        var start = event.start.dateTime || event.start.date;
        console.log('%s - %s', start, event.summary);
      }
      return callback(null, events); 
    }
  });

But this does not (doesn't return any events including those that are on the 'primary' calendar and are single, non-recurring events). The only difference from above code is singleEvents parameter is commented out so it's value will default to false. 

  var calendar = googleapis.calendar('v3');
  calendar.events.list({
    auth: auth,
    calendarId: 'primary',
    timeMin: (new Date()).toISOString(),
    maxResults: 10,
    //singleEvents: true,
    orderBy: 'startTime'
  }, function(err, response) {
    if (err) {
      console.log('The API returned an error: ' + err);
      return callback(err);
    }
    console.log(response); 
    var events = response.items;
    if (events.length == 0) {
      console.log('No upcoming events found.');
    } else {
      console.log('Upcoming 10 events:');
      for (var i = 0; i < events.length; i++) {
        var event = events[i];
        var start = event.start.dateTime || event.start.date;
        console.log('%s - %s', start, event.summary);
      }
      return callback(null, events); 
    }
  });
