Google calendar v3 Push notification expiry

Question

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.

Answer 1

by default google keeps channel expiry time for one week, How ever you can set the channel expiry time upto one month by using ttl variable

  EX: body = {
          "id": uuid,
          "type": "web_hook" ,
          "token": "something_unique",
          "address": "web hook url",
          "params": {
                     "ttl" : 864000
                     }
          }
        calendar_service = get_calendar_service(user_email)
        resource = calendar_service.events().watch(calendarId='primary', body=body).execute()

here ttl is in seconds ,and it keeps channel expiry time for 10 days
