Assistance with json format for multiple message extras about server

[jmattheis]

What kind of image is it? Is it accessible in a browser? The example you provided has invalid syntax and the priority must be an integer. E.g. this example works for me:

{
  "title": "Title",
  "message": "![Info](https://placebear.com/400/300)",
  "priority": 5,
  "extras": {
    "client::display": {
      "contentType": "text/markdown"
    },
    "client::notification": {
      "bigImageUrl": "https://placebear.com/400/300"
    }
  }
}

Per our discussion on Element:

Hi, this is a setup for Blueiris. The images in the "message" and "bigimageurl" are accessible from a web browser.
the image format is .jpg

Confirming that the provided layout was exactly what I needed and resolved my issue. Thank you so much for your help!

Here's the final version of the script in case anyone else wants to do similar. It was definitely a pain since Blueiris has it own set of variables which made it so I couldn't just script in powershell and be done. Otherwise BIs variables wouldn't work.

1. I had to create an alert action set to write to file -- powershell extension (.ps1) - (overwrite) with the code below pasted in.
2. Another action set to send the photo to the web server I use to so that it's accessible without requiring logging in to blueiris,
3. And a final alert action set to run the .ps1 powershell file from step 1 using powershell 7

A kind of messy solution I'm sure, but I'm over it after struggling with it for the last couple days lol

$TITLE="&CAM &MEMO"
$MESSAGE="![Blueiris](https://url/&ALERT_PATH)"
$IMG="https://url/&ALERT_PATH"
$URL="https://url/message?token=<token>"
$Priority="5"

$json = '{
    "title": "'+$Title+'",
    "message": "'+$MESSAGE+'",
    "priority": '+$Priority+',
    "extras": {
        "client::display": {
        "contentType": "text/markdown"
        },
        "client::notification": {
        "bigImageUrl": "'+$IMG+'"
        }
    }
}'
