Hi, this is Crawley! Crawley allows you to use your Telegram channel as a news feed for your website. Crawley is a standalone, independent from other libraries Telegram bot written in PHP. It can be used on both dedicated and shared hostings. Crawley has an API to get saved posts in JSON format and use it on your website.

Quick links: Configuration | User's manual & API | Config file

Crawley stores your Telegram channel feed into its internal database and keeps it updated via Telegram Bot API and its webhooks. It can be used as a news source for your website as well as an RSS feed. Crawley is a gate between your website and your Telegram channel that allows users which do not have a Telegram account stay in touch with you. Crawley is only an API and therefore it's highly customizable, just get Crawley's JSON and build your news page as you want!

Apache web server is the preferable because of its support of .htaccess. Don't forget to set up the AllowOverride all configuration option. Alternatively you can set up the nginx server with corresponding rewrite options, see .htaccess file in /src/ directory. It is also neccessary to restrict web server's clients from accessing the engine directory.

Crawley is tested with PHP7, but it does not use any of PHP7-specific functions. The following PHP modules are required: curl, pgsql, mbstring. In Ubuntu/Debian run this command as root:
apt install php-curl php-mbstring php-pgsql

We use PostgreSQL as the database so you also will need to set it up. MySQL/MariaDB will be added later or on your demand.

0. Make sure that your setup meets the prerequisites
1. Download Crawley and upload the contents of src directory onto your web server
2. Execute the SQL from dist/crawley.pg.sql on your database (privileges and schemas are on your own)
3. Proceed to configuration section!

If you don't have a Telegram bot yet, obtain it from BotFather. It will give you an unique bot ID:Key, remember it. Disable "Privacy Mode" for your bot to allow it to access the messages of your channel. After that, copy engine/enconfig.sample.php to engine/enconfig.php and edit it according to your requirements. Detailed explanation of the configuration fields is here. Take your attention at the TELEGRAM_CALLBACK_KEY configuration option. It should be random and it will be used in Telegram's webhook to make sure that it's really the Telegram server came to Crawley.

Let's assume that Crawley is accessible at https://example.com/crawley. Using the Telegram API make a request to register the webhook pointing to Crawley, like this: https://api.telegram.org/bot<num>:<key>/setWebhook?url=https://example.com/crawley/callback/<your_callback_key> Telegram should respond with the OK status and Webhook was set comment.

First, determine your user ID. To do that, send a /whoami command to Crawley and it will respond you with your Telegram user ID. Edit the engine/enconfig.php file and set the TELEGRAM_UBER_ADMIN_UID to the value you got from Crawley.
Second, add Crawley to your channel. In Channel Settings choose 'Add Administrators', find your bot and add it to the channel. Allow it to publish, edit and delete messages, other privileges can (and should) be disabled.
Third, send a /getkey command to Crawley in private messages. It will respond you with a key to be used to connect your channel. Go to your channel and send /setchat command with the key provided by Crawley. Don't worry, after setting up Crawley will remove this message.
That's it! You are able now to post records to the Telegram channel and they will be copied to Crawley's database.
