Telegram Notifications Channel for Laravel

Join PHP Chat Chat on Telegram Latest Version on Packagist Software License Total Downloads

This package makes it easy to send Telegram notification using Telegram Bot API with Laravel.

Contents

Installation

You can install the package via composer:

composer require laravel-notification-channels/telegram

Setting up your Telegram Bot

Talk to @BotFather and generate a Bot API Token.

Then, configure your Telegram Bot API Token:

# config/services.php

'telegram-bot-api' => [
    'token' => env('TELEGRAM_BOT_TOKEN', 'YOUR BOT TOKEN HERE')
],

Retrieving Chat ID

For us to send notifications to your Telegram Bot user/channel or group, we need to know their Chat ID.

This can be done by fetching the updates for your Bot using the getUpdates method as per Telegram Bot API docs.

An update is an object containing relevant fields based on the type of update it represents, some examples of an update object are message, callback_query, and poll. For a complete list of fields, see Telegram Bot API docs.

To make things easier, the library comes with a handy method that can be used to get the updates from which you can parse the relevant Chat ID.

Please keep in mind the user has to first interact with your bot for you to be able to obtain their Chat ID which you can then store in your database for future interactions or notifications.

Here's an example of fetching an update:

use NotificationChannels\Telegram\TelegramUpdates;

// Response is an array of updates.
$updates = TelegramUpdates::create()
    // (Optional). Get's the latest update. NOTE: All previous updates will be forgotten using this method.
    // ->latest()
    
    // (Optional). Limit to 2 updates (By default, updates starting with the earliest unconfirmed update are returned).
    ->limit(2)
    
    // (Optional). Add more params to the request.
    ->options([
        'timeout' => 0,
    ])
    ->get();

if($updates['ok']) {
    // Chat ID
    $chatId = $updates['result'][0]['message']['chat']['id'];
}

Note: This method will not work if an outgoing webhook is set up.

For a complete list of available parameters for the options, see Telegram Bot API docs.

Using in Lumen

If you're using this notification channel in your Lumen project, you will have to add the below code in your bootstrap/app.php file.

# bootstrap/app.php

// Make sure to create a "config/services.php" file and add the config from the above step.
$app->configure('services');

# Register the notification service providers.
$app->register(Illuminate\Notifications\NotificationServiceProvider::class);
$app->register(NotificationChannels\Telegram\TelegramServiceProvider::class);

Proxy or Bridge Support

You may not be able to send notifications if Telegram Bot API is not accessible in your country, you can either set a proxy by following the instructions here or use a web bridge by setting the base_uri config above with the bridge uri.

You can set HTTPS_PROXY in your .env file.

Usage

You can now use the channel in your via() method inside the Notification class.

Text Notification

use NotificationChannels\Telegram\TelegramMessage;
use Illuminate\Notifications\Notification;

class InvoicePaid extends Notification
{
    public function via($notifiable)
    {
        return ["telegram"];
    }

    public function toTelegram($notifiable)
    {
        $url = url('/invoice/' . $this->invoice->id);

        return TelegramMessage::create()
            // Optional recipient user id.
            ->to($notifiable->telegram_user_id)
            // Markdown supported.
            ->content("Hello there!")
            ->line("Your invoice has been *PAID*")
            ->line("Thank you!")

            // (Optional) Blade template for the content.
            // ->view('notification', ['url' => $url])

            // (Optional) Inline Buttons
            ->button('View Invoice', $url)
            ->button('Download Invoice', $url)
            // (Optional) Inline Button with callback. You can handle callback in your bot instance
            ->buttonWithCallback('Confirm', 'confirm_invoice ' . $this->invoice->id);
    }
}

Routing a Message

You can either send the notification by providing with the chat ID of the recipient to the to($chatId) method like shown in the previous examples or add a routeNotificationForTelegram() method in your notifiable model:

/**
 * Route notifications for the Telegram channel.
 *
 * @return int
 */
public function routeNotificationForTelegram()
{
    return $this->telegram_user_id;
}

Handling Response

You can make use of the notification events to handle the response from Telegram. On success, your event listener will receive a Message object with various fields as appropriate to the notification type.

For a complete list of response fields, please refer the Telegram Bot API's Message object docs.

On-Demand Notifications

Sometimes you may need to send a notification to someone who is not stored as a "user" of your application. Using the Notification::route method, you may specify ad-hoc notification routing information before sending the notification. For more details, you can check out the on-demand notifications docs.

use Illuminate\Support\Facades\Notification;

Notification::route('telegram', 'TELEGRAM_CHAT_ID')
            ->notify(new InvoicePaid($invoice));

Sending to Multiple Recipients

Using the notification facade you can send a notification to multiple recipients at once.

If you're sending bulk notifications to multiple users, the Telegram Bot API will not allow more than 30 messages per second or so. Consider spreading out notifications over large intervals of 8—12 hours for best results.

Also note that your bot will not be able to send more than 20 messages per minute to the same group.

If you go over the limit, you'll start getting 429 errors. For more details, refer Telegram Bots FAQ.

use Illuminate\Support\Facades\Notification;

// Recipients can be an array of chat IDs or collection of notifiable entities.
Notification::send($recipients, new InvoicePaid());
