Is there a way that the slack notifications can take advantage of using all the options in the native slack.

Here is an example

Its actually already supported, I just don’t think its documented.

  • go to: <your_ha_server>:8123/dev-service
  • Set “Domain” to “Notify”
  • Set “Service” to whatever you named the slack integration
    Under “Service Data” do something like
{
    "message": "testing",
    "target": "#notifications",
    "data": {
    "attachments": [
        {
            "color": "#36a64f",
            "pretext": "Optional text that appears above the attachment block",
            "title": "Slack API Documentation",
            "title_link": "https://api.slack.com/",
            "text": "Optional text that appears within the attachment",
            "fields": [
                {
                    "title": "Priority",
                    "value": "High",
                    "short": false
                }
            ]
        }
    ]
 }

Basically anything in this doc https://api.slack.com/docs/message-attachments can be nested under “data -> attachments” in your payload I believe.
Note looks like you have to supply the “message” part or it won’t send.

I tried that already and couldn’t get it to fire properly.

Added the trailing } and works great!

Thank you

Please show me some clue on how to integrate the fields into YAML. Somehow this breaks the config when un-commenting the comments.
Thanks.
