VK ID (OAuth 2.1 + PKCE)

На Русском

composer require movemoveapp/vkid

Register an application

Create a new VK ID application at id.vk.ru. Make sure you specify the correct redirect URI (must match exactly with the one in your config).

Installation & Basic Usage

Please see the Base Installation Guide first, then follow the VK ID-specific instructions below.

Add configuration to config/services.php

'vkid' => [
    'client_id'     => env('VKID_CLIENT_ID'),
    'client_secret' => env('VKID_CLIENT_SECRET'),
    'redirect'      => env('VKID_REDIRECT_URI'),

    // --- Extended configuration ---
    'scopes'        => env('VKID_SCOPES', ['email']),                       // default: ['email'], supports ['email','phone']
    'pkce_ttl'      => env('VKID_PKCE_TTL', 10),                            // minutes to store code_verifier
    'cache_store'   => env('VKID_CACHE_STORE', 'redis'),                    // cache store for PKCE verifier
    'cache_prefix'  => env('VKID_CACHE_PREFIX', 'socialite:vkid:pkce:'),
    'api_version'   => env('VKID_API_VERSION', '5.199'),                    // VK API version
],

Add provider event listener

Laravel 11+

Since Laravel 11 removed EventServiceProvider, use the Event facade in your AppServiceProvider@boot:

use Illuminate\Support\Facades\Event;
use SocialiteProviders\Manager\SocialiteWasCalled;
use MoveMoveApp\VKID\VKIDExtendSocialite;

public function boot(): void
{
    Event::listen(SocialiteWasCalled::class, [VKIDExtendSocialite::class, 'handle']);
}

Laravel 10 or below

Add the listener in your `app/Providers/EventServiceProvider.php`. See the [Base Installation Guide](https://socialiteproviders.com/usage/) for detailed instructions.

protected $listen = [
    \SocialiteProviders\Manager\SocialiteWasCalled::class => [
        MoveMoveApp\VKID\VKIDExtendSocialite::class.'@handle',
    ],
];

Usage

You can now use the driver as usual with Socialite:

return Socialite::driver('vkid')->redirect();

For extended scopes (e.g. apps with Business Account permission):

return Socialite::driver('vkid')
    ->scopes(['email', 'phone'])
    ->redirect();

Handling the callback:

try {
    $vkUser = Socialite::driver('vkid')->user();

    // Typical fields:
    // $vkUser->getId(), getNickname(), getName(), getEmail(), getAvatar()
    // Optional phone (if scope=phone and app has permission):
    // $vkUser->user['phone'] ?? null

    // Your app logic:
    $localUser = User::firstOrCreate(
        ['email' => $vkUser->getEmail() ?? "vk_{$vkUser->getId()}@example.local"],
        ['name' => $vkUser->getName()]
    );

    Auth::login($localUser);
    return redirect()->intended('/');
} catch (\Laravel\Socialite\Two\InvalidStateException $e) {
    // Thrown when PKCE verifier expired (user waited too long)
    return redirect()->route('login')->with('auth_error', 'Authorization expired. Please try again.');
} catch (\RuntimeException $e) {
    // Thrown when cache store is unavailable/misconfigured
    report($e);
    return redirect()->route('login')->with('auth_error', 'Temporary VK ID authorization error.');
} catch (\Throwable $e) {
    report($e);
    return redirect()->route('login')->with('auth_error', 'Unexpected VK ID login error.');
}

Returned User fields

Field	Description
id	VK user ID
nickname	screen_name (if present)
name	First + last name
email	from id_token (if scope=email)
avatar	URL to 200px profile photo
phone	from id_token (if scope=phone and granted)

Exception Reference

Exception	Cause	Recommended handling
Laravel\Socialite\Two\InvalidStateException	- state or PKCE verifier missing or expired- user waited longer than pkce_ttl minutes before pressing “Allow”	Ask user to restart login. Show message like “Authorization expired. Please try again.”
RuntimeException("VKID PKCE cache failure")	Cache store misconfigured or unavailable (e.g., Redis down)	Log and retry later. Typically a server-side infra issue.
RuntimeException("VKID PKCE cache failure: unable to persist code_verifier")	Misconfigured cache_store or permission issue writing PKCE state	Ensure correct cache driver in config/cache.php
Any other exception	Networking or unexpected JSON format	Generic fallback “VK ID login failed”

All exceptions extend base \Throwable and can be caught globally in your app’s Handler.

Extended Configuration Options

Key	Type	Default	Description
`client_id	string	–	VK App ID
`client_secret	string	–	VK App secret
`redirect	string	–	Full callback URL (must match app settings)
`scopes	array	['email']	Default OAuth scopes
`pkce_ttl	int	10	Time in minutes to store PKCE verifier
`cache_store	string	'redis'	Cache store for PKCE (see config/cache.php)
`cache_prefix	string	'socialite:vkid:pkce:'	Prefix for PKCE keys
`api_version	string	'5.199'	VK API version for users.get

Example .env

VKID_CLIENT_ID=1234567
VKID_CLIENT_SECRET=secretkey
VKID_REDIRECT_URI=https://your-app.com/auth/vkid/callback

VKID_SCOPES="['email','phone']"
VKID_PKCE_TTL=10
VKID_CACHE_STORE=redis
VKID_CACHE_PREFIX=socialite:vkid:pkce:
VKID_API_VERSION=5.199

Example User Flow Diagram

Client  →  https://id.vk.ru/authorize?response_type=code&state=XYZ...
   ↳ Redirects user back to /auth/vkid/callback?code=...&state=XYZ
Provider  →  Exchanges code for tokens (with code_verifier)
   ↳ Fetches user profile via api.vk.com/method/users.get
App  →  Creates/logs in user, handles avatar/email/phone sync
