Just a newbie programming student here tasked with creating an app that gives access to a survey that sends its data to Google BigQuery.

Currently, I just have the survey embedded on my web app via an iframe.

I'm not sure if this is the practice but regardless which APIs would I have to use and how to use it in order to collect the single response's data?

I would imagine I would have to pass in some parameter into the embedded survey url or edit the javascript in the survey to include a function that sends data back with offLoad()?
