Appflow and ionic-v1

Is it possible to use appflow with ionicv1?

I tried to link the app but it doesn’t seem to work

when I try to run ionic link xxxxx in the app folder:
You cannot run this command unless you are in an Ionic Project folder

when I try to run ionic io init:
No previous login existed. Attempting to log in now.

Initializing app with
Error initializing app: TypeError: Cannot read property ‘map’ of undefined

Even tho the credentials are correct.
