Does google-people api provide a callback to determine when the contact list changes?

Question

Other Google services provide a way to register a callback to be called when some server-side data changes. E.G. Email.

I'm wondering if the google-people API provides such a feature?

If now, how often is it acceptable to poll this API to determine if the list has changed?

Thanks

There's not push notification service in the People API yet. As a workaround If you mean to make polling requests there's a quota limit per minute per user defined in your project, it's flexible depending on your configuration. If you have a specific user to make long-polling make sure the API has the enough quota limit.
