George Jetson, you may already know this by now, but you don't need to use IFTTT to have Alexa to open your Garageio door; just enable the Alexa Skill for Garageio. Once you do this, you can say things like:
“Alexa, tell Garageio to close my [name] door”
“Alexa, tell Garageio to open my [name] door”
“Alexa, ask Garageio to tell me about my garage doors”
“Alexa, ask Garageio if my doors are open”
