Let's Short Urls

The Let's Short URL Bot is a simple Telegram bot to short your URLs.

When you start the bot you can choose between different providers like Tinyurl or cuttly, but you can also configure your own YOURLS URL shortener. When you're finished with the settings you can just send your long links and get back the shortened version.

YOURLS

If you want to use the bot with your own YOURLS shortener I have some tips for you.
Requirements for your own URL shortener with YOURLS are your own web server, a MySQL or MariaDB database and a (as short as possible) domain.

Download the latest version of YOURLS on GitHub and unzip the data.
Copy the file user/config-sample.php to user/config.php and type in your database settings.
Further parameters to set can be found here.
Upload the files to your webserver.
Go to your-domain.com/admin and log in.
Activate the plugin "RandomShortURLs" under "Plugins" and set the URL length.
Go to "Tools" and copy your API link in format https://short.it/yourls-api.php?signature=x1x2x3x4
Go back to the bot, send /yourls and in the next step paste your copied link.

Reset secret signature token

If for some reason you need to reset your signature (ie to generate a new one while making previous signature inoperative), simply modify the YOURLS_COOKIEKEY constant in your config.php. Hint: you can simply copy the result from api.yourls.org/services/cookiekey/1.0/ to generate a random unique cookie.
