Can't seem to find a way to enable sandbox-mode without fiddling straight in the vendor/friendsofapi/-folder which is a big no-no. Looks like the prod-url and not the sandbox is enabled by default.
I will see if I can sort out a quick pull request to sort this out (I'm very swamped with work right now otherwise I would've done it already) if you are open for pull requests and help.
