How to Identify Updated Email Campaign Events


We want to be able to pull new email campaign data, including events, each day. I understand that we can use the “Get email events” endpoint to return the events in reverse chronological order. Does the ordering use the created date? If so, how do we identify events that have been updated (for example, obsoletedBy is set) without pulling the entire event data set for a campaign and then comparing the values to what we previously recorded? Thanks!
