README

Allow your users to connect Telegram with your app and receive notifications;

Prerequisites

Installation

composer require furqansiddiqui/telegram

Integrating Telegram

Get Telegram instance by passing your telegram bot API key to constructor

<?php

$telegram   = new \Telegram\Telegram("YOUR-API-KEY");

Setting up a web hook

<?php
/** @var $telegram \Telegram\Telegram */
$telegram->webHooks()->setWebHook("https://www.domain.tld/telegram");

Custom Handlers

Create a handler class that extends AbstractHandler with each method for every command you wish to respond to.

  • Any user sent message that doesn't start with leading slash "/" is considered a chat message and will be handled in "chat" method.
  • All user messages starting with leading slash "/" are commands, and have individual methods as per their names.
  • Your custom handler class must have "start" and "help" methods.
  • Ideally, You should associate "chat_id" param with users in your DB.
  • On start command, you should generate a temp. authentication code and send it to telegram chat asking them to enter this code at your website after proper authentication as a user.
  • Once user enters this code at your website, you can safely associate "chat_id" param associated with this temp. code with your user.
  • How you generate/store and secure this code is entirely up to you.
  • You should name your methods in "camelCase", i.e. when user enters command "/get_balance", handler will look for and call "getBalance" method if available.
  • Any word followed by a command (after a leading slash "/") will be considered as param.
  • All parameters are stored in "params" prop as indexed array.
  • All non-command messages can be handled with in "chat" method. See BasicHandler class for an example.

Listening

  • You should use secret tokens in your web hook URL as well as cross-check data received from Telegram web hook server for security. This has to be done entirely at your own end. Calling listen/handle method assumes you have already successfully validated this request.
<?php
/** @var $telegram \Telegram\Telegram */
$telegram->setHandler(new MyCustomHandler($telegram));
$telegram->listen($_REQUEST);

Refer to class BasicHandler for better understanding on writing your own custom handler.

Sending a Message

Use sendMessage method to send a message to specific user or chat.

If you have associated a "chat_id" param with one of your users, retrieve this value to send a notification/message to that specific user at any time.

<?php
/** @var $telegram \Telegram\Telegram */
$telegram->sendMessage($chatId, "Your-Message");

NOTE: This method is ideal for Non-interactive messaging, i.e. User had previously subscribed to your bot via "start" or any other custom command and now you can send alerts/notification to this user.

For interactive messaging, You can use sendReply method in your custom handler as a quicker way around.
