Framework: Laravel App : Android

    <?PHP
function sendMessage() {
    $content      = array(
        "en" => 'English Message'
    );
    $hashes_array = array();
    array_push($hashes_array, array(
        "id" => "like-button",
        "text" => "Like",
        "icon" => "http://i.imgur.com/N8SN8ZS.png",
        "url" => "https://yoursite.com"
    ));
    array_push($hashes_array, array(
        "id" => "like-button-2",
        "text" => "Like2",
        "icon" => "http://i.imgur.com/N8SN8ZS.png",
        "url" => "https://yoursite.com"
    ));
    $fields = array(
        'app_id' => "my_app_id",
        'included_segments' => array(
            'Subscribed Users'
        ),
        'data' => array(
            "foo" => "bar"
        ),
        'contents' => $content,
        'web_buttons' => $hashes_array
    );
    
    $fields = json_encode($fields);
    print("\nJSON sent:\n");
    print($fields);
    
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, "https://onesignal.com/api/v1/notifications");
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json; charset=utf-8',
        'Authorization: Basic Auth Key'
    ));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_HEADER, FALSE);
    curl_setopt($ch, CURLOPT_POST, TRUE);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
    
    $response = curl_exec($ch);
    curl_close($ch);
    
    return $response;
}

$response = sendMessage();
$return["allresponses"] = $response;
$return = json_encode($return);

$data = json_decode($response, true);
print_r($data);
$id = $data['id'];
print_r($id);

print("\n\nJSON received:\n");
print($return);
print("\n");
?>

According to their API documentation ...one could send to different segments: EMAIL, USER TAG, TEST USERS. Their sample code hints for filters (the only option while not storing the tokens):

$fields = [
    ...
    'filters' => [
        ["field" => "external_user_id" "relation" => "=", "value" => $user->id]
    ]
];

Their FAQ also features your question:

How do I send a notification to a single user?

In PHP this shouldn't be any different, while it clearly hints for "your database" (Eloquent Model), which should be able to translate int $user_id to string or string[] $registration_id aka device registration token. This means that your MessagingService implementation/s would need to tell Laravel API about their current token - else these would be unknown when sending.

I'd rather give a Java answer to a PHP question:

Use method .setExternalUserId() to set the Laravel int $user_id, once it is known to the mobile client. When using external_user_id as filter criteria, one should also set up identity verification.

Generally one has the option to store tokens and then look them up again
... or to use .setExternalUserId(), which then can be used as filter criteria.

The mobile client either has to pass it's token - or it's int $user_id / string $email.
