how can i know when new members are added to a list via API

[Mark_Ioffe]

I am pulling from a static list via API and the updatedAt and createdAt properties are not being set as expected.  createdAt field seems blank and updatedAt is being updated but seems to have many more records updated than we expect.

Use the Activity Log Added To List type.

sorry what does that mean?  we have static lists that i'm pulling from and each records updatedAt or credtedAt don't represent the actual records that were added.  I need to know what records were actually added to the list from marketo triggers for that day.

The act of adding/removing someone to/from a (static) List is an activity logged at the Lead level in Marketo.

The Activity Log may be queried via the REST API. Added to List is one of the many activity types by which you may filter the ActLog.
