Properties

url
Type
Format
uri
Required
Yes
Description

The URL of the image placeholder. Your image placeholder needs to be hosted remotely at a web-accessible location. You can specify the URL as an absolute URL or relative to the add-on's base URL.

The url here doesn't support context parameters. However all the macro parameters will be passed as query parameters to the request.
You can use these parameters to dynamically generate the placeholder image.

Suppose you have a macro defined like this:

        "hidden": false
      },
      {
        "identifier": "param2",
        "name": {
          "value": "Parameter 2"
        },
        "type": "string",

    },
    "name": {
      "value": "My macro with placeholder"
    },
    "key": "my-macro-key"
