Laravel: How to modify notifications collection

I've got a function which returns database notifications of a user (the User model is Notifiable):

return $user->notifications()->get();

The result returned is like this:

[
    {
        "id": "5d6548d3-1f9b-4da5-b332-afbf428df775",
        "type": "Meysam\\Notification\\Classes\\CommentCreated",
        "notifiable_id": 1,
        "notifiable_type": "RainLab\\User\\Models\\User",
        "data": {
            "userId": 2,
            "commentId": 18
        },
        "read_at": null,
        "created_at": "2018-03-05 09:58:34",
        "updated_at": "2018-03-05 09:58:34"
    },
    {
        "id": "2e22e24e-a972-4a30-afeb-0049a40966a7",
        "type": "Meysam\\Notification\\Classes\\CommentCreated",
        "notifiable_id": 1,
        "notifiable_type": "RainLab\\User\\Models\\User",
        "data": {
            "userId": 3,
            "commentId": 17
        },
        "read_at": null,
        "created_at": "2018-03-05 09:38:38",
        "updated_at": "2018-03-05 09:38:38"
    }
]

What's the best way to modify this collection before returning it? For example, I want to remove the "id" field from objects, change the value of "type" field to "CommentCreated", and add new fields like "url", "username", "email", etc to each item. Is it a good idea to add hidden, visible and append attributes to DatabaseNotification model class (if so, how)? Are API Resources useful here?

By default Laravel uses the full class name of the notification as a type, If you want to customise the type of the notification in the database use this method in your Notification class:

/**
 * Get the type of the notification being stored.
 *
 * @return string
 */
public function databaseType()
{
    return 'custom.name';
}

For Laravel 5.5+

use API Resources.

For Laravel < 5.5

As suggested by @linktoahref, It is good idea is to use fractals.

By definition, REF: http://fractal.thephpleague.com/

Fractal provides a presentation and transformation layer for complex data output, the like found in RESTful APIs, and works really well with JSON. Think of this as a view layer for your JSON/YAML/etc.

You can use fractals to convert data to appropriate format, when working with laravel it is a good idea to create fractals for each models and use whenever it is required. It can accept a model and perform transformation on each fields and return in proper data format.

spatie/laravel-fractal is a good package to get start with fractals.

If you want to just change the return value of a collection, then this can be done like this way:

$user->notifications()->get()->map(function($item) {
   unset($item['id']); //remove id
   $item['type'] = "CommentCreated"; //change the value of "type" field
   $item['url'] = "url content"; //add new data
   $item['username'] = "username content"; //add new data
   $item['email'] = "email content"; //add new data
   return $item;
});
