How to set webhook url?

Hi
I’m using self hosted GitLab.
I would like to make issue from ZABBIX using Webhook.

At first, I need to set Webhook url.
In setting page of Webhook, it is showing sample url as below.
http://example.com/trigger-ci.json

Could you tell me how to set for path of url?
Thanks.
