Pushsafer notification automation

home assistant 0.96.5 using hassbian

i am trying to convert my Domoticz setup to Home assistant. the reason for the transfer is a project to read my boiler data. For notifications i have a pushsafer account. but i have some problems integrating pushsafer in my automations.
i can send messages via the services dev tool page. so i assume i have set it up correctly in my configuration.
but i recieve no messages when my automations are triggered. most of the automation file is written by the author of the boiler project. i only added the test_if_notify_works automation.
this is my part of my automation:

- id: test_notify
  alias: see if notify works
    platform: state
    entity_id: media_player.radio
    from: 'off'
    to: 'on'
    service: notify.admin_notify
      title: "radio turned on"
      message: "radio aan"
          icon: "14"
          iconcolor: "#FFFF00"
          sound: "22"
          vibration: "31"
          url: "https://www.home-assistant.io/"
          urltitle: "Open Home Assistant"
          time2live: "60"
