How to connect Apilio and IFTTT

Is this broken again or am I just missing something? When I use the app or web to visit https://ifttt.com/apiio and click “Connect”, nothing appears to happen. Then when I try to handle receiving an event from Apilio at https://ifttt.com/create/if-receive-an-event-from-apilio, the dropdown just gives me “Options Unavailable”. It never asks me to enter my API key or do any sort of authentication.
