Backend response format

You can implement 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 title, image and description fields are supported by plugin's design . 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, can contain any additional fields you want to store.
