Translating rest command to rest notify

Configuration
1

Hey, I’ve been messing around with this for too long now. I have a rest command which works perfectly, but i really want to use rest notify instead. I can’t seem to manage getting the notification to work.

I want what I write in the notify message field to replace what is 101 in the command “version”.

Advise?

  post command working perfectly:
    method: POST
    url: https://api.saf/aaaaaaaaaa
    content_type:  'application/json'
    payload: '{"command": 101}' 

  - name: notification I can't get to work
    platform: rest
    method: POST
    verify_ssl: false
    resource: https://api.saf/aaaaaaaaa
    headers: 
      content-type: application/json
    message_param_name: command
