Description

I am working on a POC where I am trying implement webhook mechanism for getting file related events in Google Drive. To achieve this result I am using "activities.watch" method from Reports API. In the guides page(https://developers.google.com/admin-sdk/reports/v1/guides/push) it is mentioned that these push notifications are not 100% reliable and some notifications might be missed.

To handle this scenario, I am implementing a polling solution using "activities.list" method from Reports API to get Drive activities for last 1 minute. By polling the activities.list method I should be able to get those activities which might have been missed from the push notifications.

Impact

The POC which I am working on needs to get Google Drive file related events such as file created/edited/uploaded and analyze these files for further processing and this has to be done in almost real time(with 1-2 minutes of event occurrence).

I would like to confirm couple of things, so could you please answer following questions,

1. Is my approach for handling missed notifications correct?
2. Is there any other/better approach to handle missed notifications?
3. Is there a restriction on no. of push notifications which can be received for a given account?
4. Are there any limitations for the push notification?
5. Is there any alternative solution to "push notification" for implementing webhook solution to get Google Drive events?

Any help will be appreciated. Thanks!
