Hi Vasile!
"1C:Enterprise Administrative Service API" is used to manage a cluster of servers, this is not what you need.
To exchange data between 1C and any online platform, you can use REST API, which provides 1C:Enterprise.
We're now preparing a publication in which there will be an example of working with 1C: Enterprise through the REST API
Do you have "1C:Enterprise Developer Guide"? This document also describes several ways to integrate 1C and other IT systems.
