Contact change source


We are trying to develope an API report that brings information of how many notes, how many contacted, how many deals had changes today, and so on.
it’s a summary of a bunch of indicators done by salesperson.

Anyways… it was working just fine because the change source was CRM_UI, but from today the change source became all the time as "ENGAGEMENTS"
and ethis srouce brings up way too much information, because we only require the changes made by a human sales person, and the requirements source
brings up a lot of more indicators.

How can we only recieve the notifications made in the user interface?
