{
    "type" : "linkTool",
    "data" : {
        "link" : "https://codex.so",
        "meta" : {
            "title" : "CodeX Team",
            "site_name" : "CodeX",
            "description" : "Club of web-development, design and marketing. We build team learning how to build full-valued projects on the world market.",
            "image" : {
                "url" : "https://codex.so/public/app/img/meta_img.png"
            }
        }
    }
}

Backend response format

You can implement a backend for link data fetching your own way. It is a specific and trivial task depending on your environment and stack.

Backend response should cover following format:

{
    "success" : 1,
    "meta": {
        // ... any fields you want
    }
}

success — uploading status. 1 for successful, 0 for failed

meta — link fetched data.

Currently, the plugin's design supports the 'title', 'image', and 'description' fields. They should have the following format in the response:

{
    "success" : 1,
    "meta": {
        "title" : "CodeX Team",
        "description" : "Club of web-development, design and marketing. We build team learning how to build full-valued projects on the world market.",
        "image" : {
            "url" : "https://codex.so/public/app/img/meta_img.png"
        }
    }
}

Also, it can contain any additional fields you want to store.
