Audit Events are worthwhile to explore in Salesforce Marketing Cloud (SFMC) if you’re in a vertical that includes tighter roles and permissions. You can supplement your audit scheme by retrieving these Audit Events via REST and writing them to a Data Extension (DE).
First, you’ll need to enable the feature here: Email Studio > Admin > Security Settings > Enable Audit Trail Data Collection > Yes
After you’ve collected data for a few days, create a Script Activity like this and set it to run on the desired interval in an Automation.
You’ll need to add your target Data Extension’s Category ID, MID, REST API Tenant, Client Id and Client Secret.
