Google calendar v3 Push notification expiry
问题 I am using Google Calendar Push Notifications. All is working well and I register my channel with no issue. Changes to the calendar result in a notification as expected. The issue is however that after an hour or so the notifications expire. In reading the documentation I cannot work out why there is an expiry given that I am not specifying one. When the channel is registered the response actually states an expiry date of 1 week from when I register the channel - e.g. Fri, 31 Jan 2014 03:23
