how-to-force-google-calendar-to-refresh-subscribed-calendar.md

Given a subscribed calendar with a url like

https://example.com/example.ics

To force Google Calendar to refresh and reload the contents right now, unsubscribe from the calendar and subscribe to a new calendar with a URL like

https://example.com/example.ics#1

Adding the anchor tag will force Google Calendar to think of it as a new calendar

Many people who come to this gist are not looking for a one time forced refresh but instead to refresh recurringly. If that's you, you should check out @derekantrican 's Google App Script

https://github.com/derekantrican/GAS-ICS-Sync

Which can refresh a calendar automatically every N minutes

Thanks to @rattrayalex for pointing people to this script

Thank you so much!
It worked perfectly!`

Great script, works great for my personal Apple iCloud calendar, but my shared family one shows as blank.

Check https://script.google.com/home/executions for errors in the log.
Apple is adding a bunch of additional data to the ics that is not always conforming to the ical standard.

Thanks, it's erroring out on something in the calendar (redacted some personal info):

derekantrican/GAS-ICS-Sync#351

Thank you. Yeah I recognized the metadata and recreated the event. Strangely that info wasn't in the invite, but some weird way my wife created it. I also commented out that exception. It sync'd perfectly after fixing that.

Thanks again.

Got one more, despite "var addAlerts = "yes"; ", the alerts are not coming over into the GCal. Am I missing something, I've tested various methods and reminder times.

Does it show the alert when opening the *.ics in a text editor?

I see this in the ICS:
TRIGGER:-PT5M

I just checked, var addAlerts = "yes"; works fine for me. What version are you running?

Not sure where the version is posted, but I copied the script off this link this morning:
https://script.google.com/home/projects/1BOk8MDLbLaHh6SwG1M1tsgNXjkcC-79LE0QoipRuTDxbO3fMVvqoROQD/edit

Here's the syntax around addAlerts:

That looks fine.
Can you share a full test event (BEGIN:VEVENT-END:VEVENT) with alarm that does not sync?

Works just fine with a fresh copy of the script you linked above. No settings changed. 🤷‍♂️

Weird. I got a fresh script and tried, and same thing. I also tried it on a different Gmail account/calendar and still no invite.
