depending on your need, a smart list would likely help.
Hi Keerthana Shanmugam,
Marketo offers an endpoint to identify a list of activities that you can get using REST API. You’ll need to first retrieve a paging token for the datetime that you want to begin retrieving activities from. You then pass the paging token in the nextPageToken query parameter. Following is the exampleGET /rest/v1/activities.json?activityTypeIds=1&nextPageToken=WQV2VQVPPCKHC6AQYVK7JDSA3I3LCWXH3Y6IIZ7YSGQLXHCPVE5Q====
You can optionally include either a listId query parameter to narrow your search to only those records included in a specific static list, or a leadIds query parameter and search for activities from only a specified set of leads. You can pass up to 30 leadIds as comma separated list.
I hope this is helpfull for you.
