TelegramLoginWidget

Laravel Telegram Login Widget. Easily integrate Telegrams login widget to send Telegram messages.

You can view a full video of the installation process an usage here, where we build an app that sends Telegram notifications from start to finish.

Installation

Via Composer

composer require pschocke/laravel-telegram-login-widget

Then publish the configuration file

php artisan vendor:publish --tag=telegramloginwidget.config

Usage

First you have to create a bot at Telegram. After that set up your login widget in your frontend.

Create an env variable TELEGRAM_BOT_TOKEN with your bots token

Create a route to handle the callback/redirect after the the successful connection between the user account and your telegram bot. Telegram uses a hash to allow you to verify the response is from Telegram. Here comes this package in play:

use pschocke\TelegramLoginWidget\Facades\TelegramLoginWidget;

class TelegramCallbackController extends Controller {

    public function __invoke(Request $request) {
        if($telegramUser = TelegramLoginWidget::validate($request)) {
            // user is valid
        }
        // telegram response is not valid. Account connection failed
    }
}

if you want more control over the response, you can use the validateWithError() method to catch more fine tuned errors:

use pschocke\TelegramLoginWidget\Facades\TelegramLoginWidget;

class TelegramCallbackController extends Controller {

    public function __invoke(Request $request) {
        $telegramUser = [];
        try {
            $telegramUser = TelegramLoginWidget::validateWithError($request);
        } catch(pschocke\TelegramLoginWidget\Exceptions\HashValidationException $e) {
            // the response is not from telegram
        } catch(pschocke\TelegramLoginWidget\Exceptions\ResponseOutdatedException $e) {
            // the response is outdated.
        }
    }
}

At this stage, $telegramUser contains a collection of all attributes Telegram provides: id, first_name, last_name, username, photo_url and auth_date.

echo $telegramUser->first_name; // Max
echo $telegramUser->last_name; // Mustermann
