Where does one get the value of the header value "MyQApplicationId" from? I see it hard coded in the flow but that can't be the same across different users

Nevermind: found that the App_ID is indeed the same for anyone! Thanks for the great flow, it works great!

I have a MyQ garage door and gate. Will this flow support both in the same flow?

Good day. I don’t have any idea for sure but I wouldn’t see any reason why it would be a problem to do so.

I made the move off MyQ months ago, so I no longer have the hardware to maintain this flow
