Receiving a Notification when an already linkedin member (via api) changes main-address or email address

We can do the following with Facebook but cannot find details about how to do with linkedin despite hours of googling. I suspect its terminology.

I'm a designer for this, not a coder, and trying to assist the final dev team with as much detail as possible in my spec.

Can we receive a **callback / notification ** if a user changes their linkedin profile details (e.g. main-address) if they have previously oauthed with our site.

Following on, if the user deletes their linkedin account do we receive an update on this? e.g. user xxx has deregistered from linkedin, so we can choose to take some action (if we so choose)

I've easily found heaps of referenc开发者_运维技巧es to getting profile info (and the fields) e.g. linkedin docs, & a ruby API wrapper, but nothing comes up with information about notifications of changes. FYI we've found out how to do this in Facebook straight from the API docs.

Unfortunately, the LinkedIn API does not support 'real-time' notifications of profile changes, de-authorization, etc like the Facebook Graph API. From the horses mouth:
