Thanks John and Sreelakshmi:
It's a sad day for me.. lol
I was hoping that I will get something from the forum to avoid doing the reverse engineer into the entire API classes hierarchy.
I am not worry so much about the Stats but as to keep the main CONTENT synchronized in both servers (Google and Ours). We would like to develop a way to AUTOMATE much of the process within our end and not accessing Google AdWords Dashboard while doing some advanced marketing topics/ideas. We have an Admin-Dashboard where we would like to program some Advanced weekly ideas and make it happen within clicks through the AdWords API. Using the API will be good to also have a way to get the latest available information in our campaigns on our end (host servers) synchronized at the most accurate/time-frame level as provided by Google.
We had already code in C# (Web) and JAVA (Android) some of the Google APIs like Google Maps, Firebase Cloud Messaging, Firebase Realtime-Database, etc. We feel ready to go for Google AdWords in order to minimize exponential time while doing our marketing ideas through Google AdWords.
Now that you guys confirmed the none DB-Schema existing, we do not have any other choice but to reverse-engineer the entire AdWords API Classes, we have considerable studied the API already and thanks to the BaseFields (base) class as well as each Field, SelectableFields, FilterableFields inside every API Class will reduce our time a lot in our first goal to reproduce a minimal database to hold our AdWords account data in our servers.
Thanks once again for the information and confirmation.
Will get back soon!
