+# TelegramWebApp
+
+```bash
+composer require socialiteproviders/telegramwebapp
+```
+
+## Installation & Basic Usage
+
+Please see the [Base Installation Guide](https://socialiteproviders.com/usage/), then follow the provider specific instructions below.
+
+## Configuration
+
+First of all, you must create a bot by contacting [@BotFather](http://t.me/BotFather) (https://core.telegram.org/bots#6-botfather)
+
+Next you must add WebApp script to your page, please see the [Initializing Mini Apps Guide](https://core.telegram.org/bots/webapps#initializing-mini-apps).
+
+> Don't forget to set your website URL using `/setdomain`
+
+Then, you need to add your bot's configuration to `config/services.php`. The bot username is required, `client_id` must be `null`. The provider will also ask permission for the bot to write to the user.
+
+```php
+'telegramwebapp' => [
+    'client_id' => null,
+    'client_secret' => env('TELEGRAM_TOKEN'),
+    'redirect' => env('TELEGRAM_REDIRECT_URI'),
+],
+```
+
+### Add provider event listener
+
+#### Laravel 11+
+
+In Laravel 11, the default `EventServiceProvider` provider was removed. Instead, add the listener using the `listen` method on the `Event` facade, in your `AppServiceProvider` `boot` method.
+
+* Note: You do not need to add anything for the built-in socialite providers unless you override them with your own providers.
+
+```php
+Event::listen(function (\SocialiteProviders\Manager\SocialiteWasCalled $event) {
+    $event->extendSocialite('telegramwebapp', \SocialiteProviders\TelegramWebApp\Provider::class);
+});
+```
+<details>
+<summary>
+Laravel 10 or below
+</summary>
+Configure the package's listener to listen for `SocialiteWasCalled` events.
+
+Add the event to your `listen[]` array in `app/Providers/EventServiceProvider`. See the [Base Installation Guide](https://socialiteproviders.com/usage/) for detailed instructions.
+
+```php
+protected $listen = [
+    \SocialiteProviders\Manager\SocialiteWasCalled::class => [
+        // ... other providers
+        \SocialiteProviders\TelegramWebApp\TelegramWebAppExtendSocialite::class.'@handle',
+    ],
+];
+```
+</details>
+
+### Usage
+
+You should now be able to use the provider like you would regularly use Socialite (assuming you have the facade installed):
+
+```php
+return Socialite::driver('telegramwebapp')->redirect();
+```
+
+### Returned User fields
+
+- ``id``
+- ``first_name``
+- ``last_name``
+- ``username``
+- ``photo_url``
