Hi @Sergio.Testori1
I moved your question to TR Internal forum.
Eikon provides Eikon Data APIs to allow you to retrieve data on the PC which Eikon Desktop is running. The API is in Python.
You can refer to this guide to get it running.
DSWS(Datastream Web Services) provides WSDL file at this URL.
There are sample codes in C# from here and Python from here.
So yes, both DSWS and Eikon provide API to retrieve data.
I cannot comment on STATA or how to import data into STATA.
