Hello all,
I contacted Jan Lolling who created many great Google components. In short, he advised me that it was possible to use tGoogleAnalyticsInput to view Adsense data since
you can get a lot of AdSense metrics with the core reporting API.
Please note you will need to link Adsense to your Analytics account. Based on my research you cannot use a Service account when accessing Adsense data however this is overridden if you link to the Analytics account and access the data via Analytics. Therefore I was able to access the data using the service account and a .p12 file.

Thanks Jan Lolling (jlolling) for your assistance!
