The app uses GitLab webhook to receive events such as a repostory push
To setup a webhook go to your GitLab project->Settings->Webhooks
Set the URL for the webhook to https://<your app server>/webhook
Set a secret token / password which the app will use to verify incoming webhook requests
Select Push events as the trigger
If you are using your enterprise SSL certificates, you can enable SSL verification
Just like the access token, the webhook can be created for a GitLab group which allows for scanning multiple repositories using a single webhook (learn more)
