Telegram OAuth2 Provider for Laravel

Note: This package utilizes an unofficial service telepass.me. Official OAuth API for Telegram does not exist.

Note: This package requires php version 7.0 or higher.

Installation

0. Credentials

Obtain your app ID and secret from telepass.me. You must set up a valid name and callback URL.

1. Composer

This assumes that you have composer installed globally:

composer require telegram/passport-laravel

2. Service Provider

Remove Laravel\Socialite\SocialiteServiceProvider from your providers[] array in config\app.php if you have added it already.
Add \SocialiteProviders\Manager\ServiceProvider::class to your providers[] array in config\app.php.

For example:

'providers' => [
    // a whole bunch of providers
    // remove 'Laravel\Socialite\SocialiteServiceProvider',
    \SocialiteProviders\Manager\ServiceProvider::class, // add
];

Note: If you would like to use the Socialite Facade, you need to install it.

3. Add the Event and Listeners

Add SocialiteProviders\Manager\SocialiteWasCalled event to your listen[] array in <app_name>/Providers/EventServiceProvider.
Add your listeners (i.e. the ones from the providers) to the SocialiteProviders\Manager\SocialiteWasCalled[] that you just created.
The listener that you add for this provider is 'SocialiteProviders\Telegram\TelegramExtendSocialite@handle',.

Note: You do not need to add anything for the built-in socialite providers unless you override them with your own providers.

For example:

/**
 * The event handler mappings for the application.
 *
 * @var array
 */
protected $listen = [
    \SocialiteProviders\Manager\SocialiteWasCalled::class => [
        // add your listeners (aka providers) here
        'SocialiteProviders\Telegram\TelegramExtendSocialite@handle',
    ],
];

4. Environment Variables

If you add environment values to your .env as exactly shown below, you do not need to add an entry to the services array.

Append provider values to your `.env` file

// other values above
TELEGRAM_KEY=yourkeyfortheservice
TELEGRAM_SECRET=yoursecretfortheservice
TELEGRAM_REDIRECT_URI=https://example.com/login

Add to `config/services.php`.

You do not need to add this if you add the values to the .env exactly as shown above. The values below are provided as a convenience in the case that a developer is not able to use the .env method

'telegram' => [
    'client_id' => env('TELEGRAM_KEY'),
    'client_secret' => env('TELEGRAM_SECRET'),
    'redirect' => env('TELEGRAM_REDIRECT_URI'),  
],

Usage

You should now be able to use it like you would regularly use Socialite (assuming you have the facade installed):

return Socialite::with('telegram')->redirect();

Lumen Support

You can use Socialite providers with Lumen. Just make sure that you have facade support turned on and that you follow the setup directions properly.

Note: If you are using this with Lumen, all providers will automatically be stateless since Lumen does not keep track of state.

Also, configs cannot be parsed from the services[] in Lumen. You can only set the values in the .env file as shown exactly in this document. If needed, you can also override a config (shown below).

Stateless

You can set whether or not you want to use the provider as stateless. Remember that the OAuth provider (Twitter, Tumblr, etc) must support whatever option you choose.

Note: If you are using this with Lumen, all providers will automatically be stateless since Lumen does not keep track of state.

// to turn off stateless
return Socialite::with('telegram')->stateless(false)->redirect();

// to use stateless
return Socialite::with('telegram')->stateless()->redirect();

Retrieving the Access Token Response Body

Laravel Socialite by default only allows access to the access_token. Which can be accessed via the \Laravel\Socialite\User->token public property. Sometimes you need access to the whole response body which may contain items such as a refresh_token.

You can get the access token response body, after you called the user() method in Socialite, by accessing the property $user->accessTokenResponseBody;

$user = Socialite::driver('telegram')->user();
$accessTokenResponseBody = $user->accessTokenResponseBody;
