YouTube API programming

Hello, I want to extract the YouTube Analytics data for my channel and videos within that channel. You can use the Java Youtube library to do it. I know the process. Below are the details YouTube Analytics have the option to "Download to CSV" where person can manually download in a folder. I want this process to be automated where the program runs - Hits the Analytics API link after he gets the authentication token - Get the Zip file for each video within that channel and also overall channel analytics - Extract the Zip and get all the CSV files in a folder. This entire process has to be automated. Please let me know if you want more details. Best, Aniket
