Get Feed Elements Updated Since Last Request

Get the feed elements updated since the last request.
Resource
To get feed elements that were updated since the last call to a feeds resource, make a request to the value of the updatesUrl property of the Feed Element Page response body. Feed elements that are updated in the same second as the request aren’t returned.

These feeds return an updatesUrl property.

This excerpt from the Feed Elements Page response body shows a sample value for the updatesUrl property:
{
...
..."updatesUrl" : "/services/data/v64.0/chatter/feeds
   /news/005D0000001LL8OIAW/feed-elements?updatedSince=2:1384811809000"
...
}

A feed element is considered to be updated if it was created since the last feed request, or if sort=LastModifiedDateDesc and a comment was added to the feed element since the last feed request. Adding likes and topics doesn’t update a feed element.
