IFTTT to Voiceflow

Hi, I would like to trgger a variable from an IFTTT webhook, how can i do it?
For example: if “AIR CONDITIONER ON” then “WEBHOOK” to voiceflow

I think Voiceflow, even Alexa itself, can be a trigger but cannot be triggered by IFTTT such as WEBHOOK.

so sad.
Is there a way to make a skill start without sayng “alexa start skillname”?

you can use Alexa Routine.

if your skill has been published(This is important), Routine can trigger your skill by schedule, by custom invoking phrases, or by smarthome device including motion sensor for Echo Flex. I think those are only ways to start a skills without invoking, currently.
