How can i call this service in Appdaemon?

action: open_epaper_link.drawcustom
target:
  device_id: 7316e6f9c04d61d256873af4c671e4fa
data:
  payload:
    - type: text
      value: Hello World!
      x: 0
      y: 0
      size: 40
  background: white
  rotate: 0
  dither: 0
  ttl: 10
  dry-run: false```

It feels like I've tried everything, but I just can't get it right :-( 
Can someone help me?
