<?php
/* (c) Raz <raz@eviladmin.xyz>
 * Based on Slack nofifier recipe by Anton Medvedev
 * Configuration:
    1. Create telegram bot by any manual in the internet
    2. Take telegrambot token (Like: 123456789:SOME_STRING) and set `telegram_token` parameter
    3. Send /start to your bot, open https://api.telegram.org/bot{telegram_token}/getUpdates
    4. Take chat_id from response, and set `telegram_chat_id` parameter
    5. If you want, you can edit `telegram_text`, `telegram_success_text` or `telegram_failure_text`
    6. Profit!
