COVER.SET_COVER_POSITION via API?

I need some help as I can`t figure this out.

I want to send COVER.SET_COVER_POSITION via API. See my postman screenshot if you can see anything wrong. I had problem with api password, but that is sorted now with longlastingtoken.

SOLVED:

Got help on facebook. “set_cover_position” instead of “cover.set_cover_position”

Hi

I’m trying to do the same thing but with a dimmer.

Can you help me?

Found the solution
set_brightness_level needs to be turn_on
