Hey @shubhanshu 
That’s a great question! You could use the Activity Logs queries in order to see all of the items that have updated in a certain period of time. You can find more info on this below in our API docs:
For example:
boards (ids: 157244624) {
activity_logs {
id
event
data
}
}
}
You can also apply the following arguments to the request in order to see the output of particular groups, columns, or even in a specific time range:
Let me know if this helps
