Employee Central - Delta Extraction

Hello,

I am working on interfaces from Employee central to third party systems . I assume the Compound Employee API is what is used to extract Master data from EC to send it to third parties in our case via Boomi.

Has anyone worked on the process of extracting only Deltas from EC whenever there is a master data change.As per the documentation it looks like the whole set of data is being extracted for the employees .

Any guidance in this direction will be helpful.

regards

Harris
