Thank you Sebastian!
I can see that from the API Explorer as well, but still not quite wrapping my head around it. Do I need to add a header parameter that first specifies what the key is (in a similar way to adding the authorisation key) then follow that with nextPageKey=(value I just put in the header)?
No, you don't need. Just add nextPageKey to url as in my example. Nothing more. First request you can execute without this parameter (you will see value for it in response). Than read this value from first response (and all next) and just add it to url.
