When Marketo merge runs, the loser record is deleted. However, the "delete" activity is not registered anywhere. The Rest API endpoint cannot retrieve this "delete" activity.
In general, Merge activity and Delete activities stored in different ways in Marketo and cannot be retrieved by one API endpoint. Delete - Rest API, Merge - Bulk activities export.
This makes it very inconvenient to track these activities in case when we need to ensure our local database is properly updated.
The suggestion is to have every "delete" to be recorded as part of the activity and be able to retrieve by single API even if delete occurred due to the Merge
Thank you
