Ntfy.sh with actions

Good day, thank you for sharing this. I’m using a rest command I found in another post. Please see below:

ntfy_notify:
  url: https://ntfy_url/homeassistant
  method: POST
  headers:
    authorization: "Bearer token"  
    username: "admin"
    password: !secret network_password
    title: "{{ title }}"
    icon: "{{ icon }}"
    priority: "{{ priority | default('default') }}"
    tags: "{{ tags | join(',') }}"
    click: "{{ click }}"
    attach: "{{ attach }}"
    actions: "{{ actions | join(',') }}"
  payload: "{{ message }}"

I was wondering if you could guide me on how to use the actions if using the above rest command.

I’ve tried to use your example:

      actions: >-
        http,Open,%ha%,body={"action":"{{action_open}}"};

by defining ha as a variable in the automation, but im failing. Any guidance is much appreciated.

Edit: never mind. got it. All i had to do is modify my actions definition in the rest command with yours.
Thank you.
