Visit config-ui: http://localhost:4000 if you deployed via docker-compose.

We recommand that you give your webhook connection a unique name so that you can identify and manage where you have used it later.
After clicking on “Generate POST URL”, you will find four webhook URLs. Copy the ones that suits your usage into your CI or issue tracking systems. You can always come back to the webhook page to copy the URLs later on.

For more usage: plugins/webhook.
