Getting updates via Webhook

The first thing you'll have to do is register a webhook with Telegram via the SetWebhook method:

use \unreal4u\TelegramAPI\TgLog;
use \unreal4u\TelegramAPI\Telegram\Methods\SetWebhook;

$setWebhook = new SetWebhook();
$setWebhook->url = '[YOUR HTTPS URL]';

$tgLog = new TgLog(BOT_TOKEN);
$tgLog->performApiRequest($setWebhook);

This will leave you prepared to start receiving updates on the chosen URL:

use \unreal4u\TelegramAPI\Telegram\Types\Update;

$update = new Update($_POST);

Now $update will contain the actual Update object. Hope that wasn't too difficult :)
