RD ATOM will plugin to any ITAS database to extract the taxpayer identification numbers and contact details, to make it available to other systems through its API data service.

The ATOM API allows other systems, for example xCAS or the revenue authority website to access, search and use the taxpayer registration details. This is important because other government institutions should be allowed to verify taxpayer registration status electronically, and ensure that service is not offered to entities not registered. ATOM is quite unique since many ITAS systems do not have such an API. 

Yes, that is the idea. Using ATOM as plugin is easy, and you will see all your data in the user interface. You can then test the system before deciding if you want to switch to issue taxpayer registration certiicates within ATOM.
