Hi @Dev 

While we don’t really expose the API-related details for any APIs in general (as the whole point of the application and platform is to hide the complexity of the data source APIs), we expose some aspects of these APIs in our Help documentation:

• Authentication guide: https://cdn.cdata.com/help/RTH/synch/default.htm#pg_connectionsync
• Data Model: https://cdn.cdata.com/help/RTH/synch/default.htm#pg_datamodel

P.S: The Help doc links are for CData Sync (as the question was asked under the CData Sync platform). If you are interested in help links for any other platform, happy to provide those. :)

Thanks for the information @Ankit Singh
