I think this looks good, my only hesitation is maybe wondering whether we're now sending too many headers - the data lake doesn't necessarily an auth header, really just the basic headers like the client_id and the Kickstarter-iOS-App etc. 🤔 Maybe at a later date we can refactor our default headers to decouple the authentication headers from the basic ksr headers required to validate the client sending the requests.

Hello, it's me with an annoying question 👀the client_id is a query param and not a header, right? Wanted to make sure I'm doing the same when I open my PR

That's correct, client_id is a query param!
