#next_sync_token fo Google Calendar Events always return nil

Question

I created 3 events in Calendar, then I run

response = @client.execute!(
   :api_method => @calendar_api.events.list,
   :parameters => {
     :calendarId => "primary",
     :maxResults => 10,
     :singleEvents => true,
     :orderBy => 'startTime'}
 )

I received 3 items but #next_sync_token method called on response.data returns nil (#next_page_token also returns nil but in this case it is correct). I tried to set :fields parameter to "nextSyncToken" but still nothing. I also made some updates on that events and #next_sync_token was still set to nil..Am I wrong? Maybe I made some mistake ? The call only with calendarId in parameters do the same.

Get rid of orderBy. This isn't documented, but if you try the Google API, you'll see that nextSyncToken isn't returned with orderBy: startTime.

Wasted lots of time on the same issue.

This was definitely the problem for me! Thanks for much for posting this. The Google Calendar API docs need work. – Sam Jan 06 '16 at 23:12

The result will only have the next sync token on the last page. You need to go over all the pages (until next_page_token nil) and then you will find a sync token.

Yes It is true and I know this, but here I have only 3 events so I have only 1 page and it is the last. In this case I think that #next_sync_token should respond with proper token. I also see that response.body contains nextSyncToken, so that method should work – Janek Kurzydło Dec 01 '15 at 14:21

One more thing to try if you aren't getting the next_sync_token is to add it to the fields parameter:

Example:

params = {
  max_results: 100,
  fields: 'items(id,summary,description),next_sync_token',
}

result = calendar_service.list_events 'primary', **params

#next_sync_token fo Google Calendar Events always return nil
