pact-broker - 如何为自托管的契约代理创建 webhook？

Question

我已经成功设置了一个契约代理，但我不确定应该在此处添加什么以将 webhook 集成到现有的 Gitlab CI 中？

{
 "consumer": {
    "name": "consumer-app"
  },
  "provider": {
    "name": "provider-app"
  },
  "request": {
    "method": "POST",
    "url": "", // I suppose this should be somewhat related to GitlabCI but I'm not sure what to add here?
    "headers": {
      "Accept": "application/json"
    }
  },
  "events": [
    {
      "name": "contract_content_changed"
    }
  ]
}

非常感谢任何有关如何设置它的想法。谢谢！
