1. Generate ssh keys for www-data:

sudo mkdir /var/www/.ssh
sudo chown -R www-data /var/www/.ssh
sudo -u www-data ssh-keygen -t rsa

2. Add that ssh key to the Deploy keys for your account or repo
3. Put this WebhookController into your app and fill the secret with random data
4. Create Webhook, put secret from controller into the Secret field. URL has to be like this:

site.com/webhook

5. Add access to your repo for www-data user:

chown -R www-data /var/www/yourrepo/

All done!
