I'm using the following (non-APEX) REST connection to retrieve chatter records from a unique chatter group (id.) How can I limit the number of chatter records retrieved? I only want to use the last 20 chatter records for a portal feed.
GET https://<my url>/services/data/v39.0/chatter/feeds/record/0F9G0000000PeqbKAC/feed-elements
