Dick the Deployer

To notify Dick the Deployer about the changes in repository you can use generic hook. To do so please send POST request to api/hooks endpoint, with json body:

{
    host: 'my-gitlab.example.com'
    path: 'open-source/wizzard'
    ref: 'master'
    sha: '44a5d78fd58cb9d5de4'
    lastMessage: 'Wand support implemented'
}

You can automate this using post-commit hook feature. Docs are avaliable here.
