Download adsense earning using API OAuth 2.0

Goal of the project: Work with X number of adsense accounts that are not connected. Request a report according to setting file (Startdate,EndDate,currency,Dimension,Metric etc.) Using [login to view URL] This job is intended for someone who did it in the past. Payment will be released only for 100% of the job done. For me the job is done if: 1. Token is saved meaning for each adsense account I'll only have to manually authorized once (or not at all) 2. I can with one click download reports for all of my adsense accounts. 3. The reports are according to the setting file. There will be a larger followup project if I'm happy with the results
