I'm trying to see historical data on Microsoft CRM. I have activated Audit settings and I realized that I can't see by Odata or API Feed. But if I know the ID of Audit ID I can get the Old Value and New Value that is referencing. 

According to the following blog post using the API Call RetrieveAuditDetailsRequest.


Also, this thread on StackOverflow says something similar:stackoverflow.com/.../how-to-get-audit-record-details-using-fetchxml

I don't have a lot of experience on C++. How could I try an API Call from Visual Studio? (I have Visual Studio 2017 Community). The connectors that I have are for modifying the CRM rather than accessing data.

I also found the following tool, but also is not retrieving audit historical data
